Hello I have an intermittent misfire. My code reader reports p0352.
The problem.....
On initial cold start, it starts on 3 and within a few seconds fires up to 4.
Once warm and the car is restarted, the misfire is pretty much constant. (This makes me think heat related).
What I have tried so far.....
Swap coil packs over - No difference, still get p0352 (even after clearing code). In my mind that takes the coils out of the picture.
When misfiring, I've pulled the leads (using insulated gloves), the misfire is from number 2.
Pulled plug 1 and 2, visually checked OK, in fact they look new.
Swapped plug 1 & 2. Still same fault/code.
Visually checked 1 & 2 HT leads.
Swapped lead 1 & 2. Still same fault/code.
What I am now thinking.....
Compression testing all the cylinders.
Injector fault.
Wiring fault.
The fault doesn't match the ECU failure posts I've read.
I bought the car with a suggested injector fault. So I would not be surprised if that is the problem. Searching the forum, injectors are suggested, so is the ECU (see above). I've also seen mention of injector cleaner solving the problem.
Before I start the process of digging deeper into the engine, I thought it would prudent to ask people who know this engine better than me. One confusing bit of information I found suggests this is a SPi engine, it certainly isn't.
Thanks in advance.
Dave
