I dont know if I am posting this in the right place but after replacing one of my fuel injectors and putting everything back together my 87 iroc z starts great but then dies. if i unplug the MAF connection it runs but idles and revs like crazy. i replaced the MAF but the sames thing happens, starts then dies. Checked the voltage on the connection wiring and it says it okay. what else could it be? Seems like some sort of computer problem. but what???
