PLEASE HELP. I HAVE BEEN GETTING ZERO RESPONSES ON HERE LATELY.
I am at my wits end here and can only look now to either the FPR, ECT, CCRM, or COILS as see the following I've replaced quite a lot recently.
Description of Problems:
1. Engine attempts to stall IMMEDIATELY following the radiator cooling fans turning OFF. This has made me think perhaps the CCRM is going bad because I don't know what else would do this unless its an electrical (bad ground) issue.
2. I'm getting 9 - 11mpg on a new Jasper engine
3. Idle pulses/hunts constantly in Park from 600 - 800 rpms
4. Sometimes under accel/load driving the van jerks as if the key were turned off causing deceleration for 1-2 seconds. Its actually hard to describe what it does, but its as if it can't make up its mind about going forward or like it isn't getting gas.
I'm not sure if the 2 (MPG and idle pulsing) are related, but I believe them to be.
New cats (Magnaflow ypipe)
New cat-back exhaust upgrade (Borla discontinued model)
O2s in good shape and cleaned at tops (NO CEL)

New water pump
