You will have to check for any vacuum leaks and check the EGR valve. if it stuck open due to dirt/carbon or just a sticky shaft it will cause a vacuum leak.

I have a1988 s10 i am trying to get timed but when you try to start it it back fires thru the throttle body


This is only a suggestion but I had a similar problem. I have a 1987 Camaro Iroc z fuel injected. I had a similar problem with the car back firing through the throttle body. It turns out it was the TPI sensor mounted on the front of the throttle body. The sensor is mounted on the front of the throttle body to the left on my car, the opposite side of the linkage. Its black in color and has a electrical connection to the back side of it. Its triangular in shape and mounted with to hex head screws if this is of any help to you locating it. Try adjusting it first that may correct your backfiring problem like it did for me. If this was any help to you leave me some feed back.

Head seals?? Do you mean head gasket? So it overheats & high idles? It almost sounds like the wrong head gasket was used (its possible) also, if the vehicle overheats, have you looked at the water pump? I would worry about the overheating more than the high idle.

this might sound stupid, have a look in the exhaust and see if the muffler (ime from uk so hope thats a correct term) internals have not collapsed or you have a blockage in it. this might be a problem, have you got a cat converter on it? that might be doing the same, if its gasoleen or diesel it might be the cause, just a guess as not been able to see it in flesh...

HIGH IDEL


sometimes the gasket under the trottle body goes bad. spray carb cleaner at the base of the trottle (not down into it) body while the engine is running. if the idle changes your on the right track. its an easy gasket to change.
