i hace a 87 rs v6 5 spd that backfires and and when im crusing at around 25-30k rpm or if i accelerate to around 40-45k rpm it jerks and loses rpm kinda like someone who just started drivin a stick any ideas whats wrong? had a buddy look at it and he said a valve to a fuel injector was very dirty and it sticks a lil could that be it? no engine light either

Not to take anything away from this website but I found a very useful site that is all about the 3rd gen. Camaros. I recently bought a 89 RS T-Top 1 owner car and this website has any info you want to know. Hope this helps. http://www.thirdgen.org/
