My car starts and idles so-so, but as soon as it hits closed loop, it starts to hunt for idle, stumbles and dies. I went through with my mityvac today and checked all of the lines, which are new and there didn't seem to be any leaks. The car also seems to have a slight miss that mostly goes away as i rev it up, but once it gets warm i have to keep revving it to keep it running. The PCV valve is the correct delco part number. I was thinking maybe the maf? since it is a napa reman. unit with the stupid bottleneck design (I can't afford an oem one just yet). The car won't start or run with the maf unplugged. The ECM is one i got from a board member who tests them before selling them. Does the MAF sound like a possible culprit, or maybe ignition module? Any ideas would be greatly appreciated.
