Hi my name is todd i am having problems with my 1987 chevy blazer 2.8 liter v6 with a 5sp tranny and was hoping someone would know whats up.I bought this truck for 600.00 bucks a couple months ago it passed smog runs ok but.It wont hit 65 mph.It seems like if i back it off to barelly any gas it will pick up a lil but from a quarter throttle to full throttle nothing.Yet when its cold or first started it has plenty of power will even spin tires but after warm its a dog.Egr valve is good checked that with vaccum.Just put a new ignition control module that didnt help.My family's local mechanic said my prob is my pipe is pluged at the Y.I had my cat taken off so only have straight pipe.Another mechanic said he has been doing it for 30 years and no way could it be pipe.I dont know.A check engine light came on and i coded it.I got code 12/32/42 So wierd what can cause lack of power like that from heat?I cant figure my problem is it fuel or timing or exhaust what can anyone help me please.I am starting work up in the mountains and sometimes i am dropped down to 35 mph just trying to get up the hills.
