still surging
ok so ive got a 91 tpi 350 ive cleaned the injectors and changed the plugs/wires it hasnt actually died on me "yet"but its getting worse.it runs just fine while driving but when i get to a light or put it in park the rpm goes high then real low and almost dies over and over.it never usually happens when the engine is cool but as soon as it gets a little warm...how can i fix this?

Re: still surging
check the codes. if the coolant temp sensor is bad or open circuit it can cause that.

Re: still surging
Check the IAC. The spring may be full of carbon and need cleaning/replaced.
