I think with your help i got my problems narrowed down to a few things. i finnaly have some time to work on my 92 Super coupe. so before i start spending a load of money let me make sure the parts im gonna buy are correct. 1st, my problems are check engine light (CEL) comes on and off. my car sometimes hesitates if you are making boost. my boost gague is on 15 at idle and only goes barley past 10 at WOT. sometimes my car wont start easy it just turns over for a long time with black smoke coming out of the pipes until it finaaly starts. my car idles really rough. my 8mm ACdelco wires will shock me if i touch them with the engine on. my car seems to not have alot of power and i cant get a tire scratch shifting in 2nd. ran codes on KOEO and KOER and didnt get anything. solution (i hope): 2 new o2 sensors, new camshaft sensor, new magnecor 8.5 mm perfomance wires and some autolite double platniums, and check fo boost leaks. new problem: dont have that much money. does any one know if i need all these parts or could one thing inparticular be the cause of these problems. also can some one give me some tips on changing the camshaft sensor. im going crazy because i cant figure out whats wrong with my car. also can someone give me some tips on trying to find and cure boost leaks. the FAQ didnt really make that much sense to me. thanks.
