Hey guys, havent posted in a long time due to most of my problems being answered by reading various posts, but i've got an issue with starting the car at the moment that just seems to be getting worse.

When i turn the key it winds over for about 4 seconds, then slowly starts to fire up. It's very rough as it starts, and seems to kick in a couple of cylinders at a time.

The car has near new NGK plats, new coils, injectors have all been pulled and cleaned & tested by an automotive tutor at 'polytech' (our trade level education facility) and its also had a new knock sensor installed and a new o2 sensor. Fuel pump tested strong, and fuel filter is regularly changed, but despite all this, it still starts hard, and occasionally the exhaust smells rich and pops a bit..

So, anyone had this problem? What am i missing?

cheers guys.

Scott.

 

water temp sensor?

 

Can you please explain this? Car seems to do it whether its hot or cold?

Cheers Jeff

 

Uses this sensor to determine whether the engine is hot/cold in order to run the cold or hot start programs. If you have problem in both hot/cold engine conditions, it's probably something else. ie.. aux air idle control valve? or any number of 5-6 different things.

 

Yeah, good point. Might have to ship over an FSM too, as this haynes is pretty hopeless.. Will keep testing i guess. Thanks for the quick replies!

 

Try the gen main sticky. It has the autozone fsm that I've been telling people about for the last week or so. Mizere-x credit.

 

Thats awesome, thanks for that link! Guess its not only newbies that should read the stickies!

Just quickly looking through there, i had a thought, could the power transistor cause this, or would it just prevent startup all together? Might get my multimeter out and go test it..
