Re: 1988 gmc k2500

I put some helicoils in the top of the transmission, now the stick doesnít flop around so bad. For the high idle, I tried to test the AIC. I checked the signal at the connector with volt meter and saw pulsing. I shorted the ALDL pins A and B, turned the key, and disconnected the AIC after a minute. I pulled the short, and started the engine, but the idle remained high. I sprayed starting fluid around looking for vacuum leaks. I replaced the AIC, but the idle remained high. I took the truck to a repair shop. They replaced the AIC, said the one I put in was bad. Itís running good now and Iím ready to start the frame swap.
