fluctuating idle only when cold????
Okay,
I know idle rpm has always been a popular topic, but this one is stranger than the usual one. Only when cold, my idle is all over the place, then the engine will just die. Start it up, and the idle goes everywhere and then almost cuts out then shoots back up again. Once the engine is at operating temp, it idles perfectly. I've cleaned the IAC, TB, MAF, and air filter. This just started three days ago. I'm going to replace the ect and check/clean the tps. Is there any way to troubleshoot the MAP sensor? It bucks now while trying to hold steady cruising rpm's 2-3k...I'm starting to think fuel pump maybe??? It just dies and then comes back all of the sudden... Figure this one out... thanks...
