Not too long ago my Toyota MR2 was having a weird problem. The car would be able to start, but after running for a while it would stall, and have very bad air fuel mixture, black smoke and all. After consulting with several owners, one suggested that I check for leaked capacitors on the ECU as that might be one of the causes.

ECU located at the rear boot

The ECU on second generation Toyota MR2, in this case a 1991 3S-GTE version, is located at the rear boot wall that is seperating the boot from the engine, just behind the carpet. You will need a Philip screw driver and if I remember correctly, a 9 or 10 mm wrench to undo the mounting.

look at the 3 connectors at the bottom of the ECU

There are 3 connecting sockets located at the bottom part of the ECU. You should be able to disconnect them without much effort. The 3 connectors are of different sizes, you can’t go wrong when putting the thing back together. Do note that you should always disconnect the car battery and properly ground yourself before diving into such endeavour.

the 3 connectors

The ECU consists of two PCB boards, take off the 2 screws connecting both and you will be able to expose the innerds. In my case, I did not find any leaking capacitors. The problem was later found out to be caused by a faulty airflow sensor.

Mazda 6 is the Japanese car maker’s flagship sedan going head to head in the market dominated by Honda Accord and Toyota Camry. I was fortunate to test drive the 2.3 liter Mazda 6 a couple weeks ago at the Mazda showroom in Petaling Jaya during their launching of the long awaited Mazda 3 in this country.

the handsome Mazda 6

The 2.3 liter powertrain is good for around 166 hp, similar to the 2.4 liter iVTEC engine from Honda Accord. The Mazda, however, feels a lot more zippy during acceleration (8.9s to 100km/h). This might due to the curb weight of 1390kg, some 60 kg lighter than the Accord. As I floored the accelerator while in the fully automatic mode, the engine revved up to almost 7,000 rpm before switching gear, I guess the 6 does deliver some zoom zoom spirits.

a nice driver’s car

The 6 speed triptonic gives you the flexibility to change gears when you feel like having some spirited drive, and it is intelligent enough to not let the driver over-rev or bog down the engine. As I found out when putting the car on 2nd gear driving up hill, when the I stopped the car, it automatically dropped to 1st. Very nice. The car feels pretty good around the bend too, does not have too much body roll for a car it’s size.

the cockpit of Mazda 6

The car looks great on the outside, the interior does not dissapoint either. The 2.3 liter version comes with full leather interior, including all the seats, door panels, and even the shifter and handbrake. In dash 6 CD changer comes standard with a pretty decent in car steroe system.

6 speed automatic with tiptronic

The cockpit backlight is red in color and are pretty driver oriented. Other than the standard speed, techo, water temperature and fuel, the gear is also displayed, very useful while on tiptronic mode. Stereo and auto cruise controls are conviniently placed on the steering wheel.

the center console

Instead of the usual 2 air conditioning vents in the middle, the 6 comes with 3, this is pretty good for the rear passanger. However, there is no individual climate control like the one found in the 2.4 Honda Accord. There is only one single temperature control.

Priced at around RM 160-170 thousands, the Mazda 6 2.3 is in direct competition with the 2.4 Toyota Camryand Honda Accord. While 2nd hand value of Mazdas might be lower in this country as compared to the other two Japanese brands, the Mazda 6 does offer a very good alternatives for it’s performance and arguebly higher asthetics. If only they offer the 2.3 turbo version that puts out 273 HP..

The Toyota MR2 club organised a convoy to Ulu Yam at Selangor on the New Year’s day. Though most of us had partied the night before, about 13 cars and over 20 people still managed to show up for the fun drive on the first morning of 2006. There were 3 MRS, an MK1 MR2 with super charger, 7 SW20 MR2s, an EVO, and an S2000. By about 11am, we have had our breakfast at McDonald’s near the Curve and was on our way to the Petronas petrol kiosk before heading off to Ulu Yam.

filling it up for the trip

I had some trouble starting up the car at the petrol kiosk, but after the guys removed and put back the relay, it seems to be fine again. So we started our journey to Ulu Yum. About 20 kilometers later, we regrouped at Selayang. It was there my car stalled at idle and refused to be started again, most probably due to some electrical problems. We left our car there and I followed another member to continue the convoy.

this was where my car stalled

By the time we regrouped again at another petrol station. Another MR2 faced with a mechanical problem and had to abort the convoy as the clutch would not engage. The car had to be towed back, it was lucky we weren’t at the hilly area of the jorney yet.

We then reached Ulu Yam and had lunch at Hock Lay restaurant. Ordered steamed fish, asam prawn in coconut shell, vege, deep fried squid, guiness chicken wing, and tofu. It was very good, and at RM 15 per person including drinks, pretty reasonably priced too. We then decided to go to Fraser’s Hill instead.

negotiating the bend

At Ulu Yam the elevation was only 75 meters above sea level, by the time we reached the foothill of Fraser’s, it was already 800+ meters up and the temperature was pretty nice and cooling, feeling like air conditioned atmosphere. A very welcoming breeze especially when KL averages more than 30 Celcius.

As the road going up to Fraser’s hill (8km) is small and only wide enough for a single car, the authority sets up a system whereby the traffic is alternate every half an hour between going up and downhil. We waited at by the gate for quite some time before we got to go up to the top. The drive up the hill was curvey and very tight. The guys enjoyed it alot.

installing the spare tyre inside out

Well, 3rd time is the charm. Sure enough, we had the third casualty of the day. Another MR2 had a flat tyre on top of Fraser’s hill. We put in the spare tyre in the reverse way since it wouldn’t fit otherwise due to the rear brake. It had the maximum offset look that was rather hillarious. By then it had started drizzling and was pretty foggy. We decided to call it a day.

About an hour later we go back to where I left my car. Luckily, after resting for some 8 hours, I was able to start the car without too much trouble, and drove all the way back home pretty smoothly. However, the car stalled again in the car porch at home. Will have to get a mechanic to sort out the problem soon.

In late 2001 to 2003, I had the privilege of owning one of the finest Japanese sports cars produced in the nineties. The Dodge Stealth RT/TT is just a rebranded version of the more widely known Mitsubishi 3000 GT VR4, or as it is called in some other countries, the GTO twin turbo version.

Some quick specs:

• Engine: 6G72 3.0 DOHC twin turbo
• Compression: 8.0 to 1
• Drive train: AWD with rear LSD
• Turbo Boost: 1.0 bar
• Power: 320 HP @ 6000 rpm
• Torque: 315 lb/ft @ 2500 rpm
• Transmission: 6 speed Getrag close ratio
• Tyres: 245/40 ZR 18
• 0-100 km/h: 5.5s
• 1/4 mile: 13.6s

The Stealth I had was basically completely stock, down to the original air filter and the quad-exhaust. I had intended to do a stage one upgrade to get a few extra horses, but due to unforseen circumstances, the plan went up the air and I decided to come back to Malaysia instead. An open pod K&N filter, after market exhaust, and a boost controller will easily push the power output to the 360+ level.

Many had thought that the Stealth/GTO/3000GT is a sports car, but Mitsubishi had designed a touring car instead. In fact, GTO stands for “Gran Tourismo Omologato”, which basically means Grand Touring class production vehicle. True to it’s spirit, the car is excellent at sustaining high speed travel. I have taken her through long journey, from Cincinnati to Chicago, and to Washington DC metro area. Each way was over 1200 km, and the vehicle takes it gracefully.

The interior of the car sports full leather seats for the driver and the shot gun, they are rather spacious and comfortable, while back seats are only fit for kids. The driver seat is also fully powered, you can adjust it’s height, tightness and firmness electronically.

The cockpit displays the speedo meter with 180 mph as the limit. I’ve personally only tested her to around 145 mph before my balls shrunk (don’t ask.) Rev limit stood at 7000 rpm with the ECU rev cut at 7,300 rpm. There’s also the standard water temperature, fuel gauge, oil temperature, batter meter, and boost indicator. Climate control and cruise control comes standard, and it includes a 6 speakers Infinity head unit with 6-CD changer too.

Speed when I needed it, comfort for long distance, with an aggresive look that is the pinnacle of the Japanese sports car era in the 90s. It was truely a sweet ride.
