Vacuum leak?
Vacuum leak? I am still trying to figure out what is making my engine run so rich. I thought it was the cracked exhaust manifold throwing off the right bank O2, but I replaced the manifold and nothing is better. Could a vacuum leak cause the engine to run rich somehow? Also my idle is kinda unsteady sometimes so that would also point to a vacuum leak wouldnt it? It is not a smooth idle, it sounds like I have a mild cam in but it is stock, everything is stock except for the exhaust. I am trying to pass emissions but I dont much money, Thanks.

i am having the same problme with my car my idle is messsed up an dreally shifty and it is runnign a little rich...i have a tear in my elbow....also u could clean out ur Throttle body and ur IAC..which is underneath ur TB. Those were 3 things my buddy said to check for
I thought unplugging the neg. terminal on the battery for more than ten seconds resets the adaptives? If I am wrong how do you do that? I have a 93 so I cant reflash or anything, that is the only thing that I do not like about 93s.
