How’d I get inside this tube?!?!
I just got rid of my 1995 Silverado for a 1991 Chevy K2500 and its been running great! besides the weak reverse nothing has been wrong. yesterday we cut off the stock muffler and put on a Flowmaster which sounds amazing BTW, now it has an idle around 2000 RPM and its really killing the tranny, i let off the brake at a stop light and it spins tires. i replaced the CTS (Coolant Temp Sensor) and it finally went down to around 900 rpm, then i shut it off thinking it was good and it shot back up to 2000... ive rebuilt plenty of TBI engines and this is the first that has actually stumped me like this. any insight will be appreciated. thanks again!
