Gudetama Posted March 26, 2017 Share Posted March 26, 2017 The previous owner said it ran good. I tried turning it on and it only stays on if I give it gas. I've already replaced the MAF and cleaned it out good, the battery is fully charged and I just don't know what's wrong with it. Any suggestions?

sha4000 Posted March 27, 2017 Share Posted March 27, 2017 What did you clean the MAF with? If it was not bad you might have killed it. You can't clean the MAF on the first GEN with any kind of solvent. Is your check engine light on? If so get the codes read or read them yourself. http://www.lexls.com/tutorials/intro/codereading.html Quote Link to comment Share on other sites More sharing options...
