CA18DET Breaking up and boost issue

Recommended Posts

Hi,

just looking for a little help to find out what my issue is.. will start fine no problem, idles good when cold and as it warms starts to misfire. Tried driving it down the road and keeps breaking up under any acceleration. As you are about to hit boost just gets worse and won’t go any further than 3000rpm. 

Had fuel pump changed, changed MAF, vacuum leaks fixed, Ignition timing reset, new spark plugs (but look pretty black already?). Have done compression test and all cylinder are pretty much equal. Been recommended to get FPR also. 

Any ideas why it’s not happy? Cheers

If it won't go any further than 3000rpm then it sounds like the ecu is in limp mode. You can google how to get diagnostic code out of ECU and see if that helps narrow it down.

Mr sleeper 

Thanks for that, actually didn’t think of that.  I’ll have to have a look at that tomorrow. Cheers
