Peter10654 Posted December 27, 2006 Share Posted December 27, 2006 Hey Guys, a friend of me have a EU Spec (same as UK Spec) 6-Speed Supra and we have a lot of probs with the car. First of all it start wonderful but during idle there was all 5 -7 seconds a "engine shake". The problem is also during driving all the time. sample: I drive with around 40 mph and try to hold this speed, it feels like something brake the engine for few milliseconds and this sympton all the time. The engine can't hold a smooth running. Something is stuttering. Its hard to describe. Boosting the car was fine. The problem is only during idle and slow driving around. Maybe somebody knows something. Thanks Peter Quote Link to comment Share on other sites More sharing options...
Scooter Posted December 27, 2006 Share Posted December 27, 2006 possibly coil pack connectors? try these? Quote Link to comment Share on other sites More sharing options...
Peter10654 Posted December 27, 2006 Author Share Posted December 27, 2006 Thanks for you answer, but the Link doesn't work. Got an error message from the forum I will check the coilpacks, and connectors. Maybe someone has another idea Thanks Peter Quote Link to comment Share on other sites More sharing options...

Alex Posted December 28, 2006 Share Posted December 28, 2006 Hey Guys, a friend of me have a EU Spec (same as UK Spec) 6-Speed Supra and we have a lot of probs with the car.

Maybe somebody knows something. Thanks Peter It's not the coils - it wouldn't boost if it was. I assume it's in vacuum (negative pressure) when at 40mph. I don't think this sounds like an ignition issue...unless the spark is failing due to a battery/alternator issue low down the rev range?? I'm pretty sure though that modern engines/alternators can charge a battery at even low rpms...might be worth a look. Does the Euro spec car have a fuel computer? is it modded in any way? If I was to guess, I'd say it was a fuelling issue under vacuum. Either the Fuel Pump ECU fails when in 9v mode (The Fuel Pump ECU gives 9v's to the fuel pump off boost and 12v's on boost). Or the FPR isn't working/connected properly. Quote Link to comment Share on other sites More sharing options...
Peter10654 Posted December 28, 2006 Author Share Posted December 28, 2006 Hi Alex, thanks for your statement The car is absolutely stock expect the v-max limit on 250kph was removed. No Fuel computer, both cats are in and everything is stock. The car have had an accident and was repaired/painted with removing the engine. Maybe something was going wrong during assembling, but what.... ? What would be first to check ? Thanks Peter Quote Link to comment Share on other sites More sharing options...
Alex Posted December 28, 2006 Share Posted December 28, 2006 Check that you get 14v from the alternator when the engine is running. Check that the battery is passing 12+v's between it's terminals. Does it have any trouble starting? Which plugs are fitted? Check the vacuum hose to the FPR is on securely. Quote Link to comment Share on other sites More sharing options...
