Want to know if anybody can give me ideas to a cold hard starting on my 92 5.0 manual? It has a hard cold start as if takes a while to start, many turns and finally starts. Then idle would go up and finally down after a heating up a bit. Then on warm engine it would start normally. During driving it drives good, no idles issues, bucking, etc. Perhaps its my EGR valve, Idle air control motor or even the TPS? please help
If this fails, you should see a check engine light. If your getting that, I would check the code and validate it is indeed the TPS sensor. If it is, this is a quality piece and I have ran it on several cars over the years with no issues.
