Does anyone know where I could find an illustration of all the timing mark indexes chevy has ? I have a 88 Chevrolet V-30 (87 Body style K30 Cab and chassis) duely truck with a TBI 350, vin code "K" engine which is having a really hard time getting thru our new emissions test. The timing mark index is all rusted and I cant read the degrees on it. I can not find anything in the books that look like it. This truck is so wierd. Its like its a normal truck engine in a heavy duty truck and every time I go for parts they guys tell me "You dont have that in your truck" but I really do.
Anyone in here really good with '88 GM TBI emissions ? I do have some questions about stuff I cant find in the books/web ie: why does my IAC go way up, 100+, when I am in cruse mode (on the highway at 65mph). Shouoldent it be 0 off idle? Think my injectors are leaking?
so much to learn and so little time.
Thanks in advance for your help
Pam
