92 TPI coughing sputtering after a few minutes
Have a TPI on a Chevy 350 on my ****** truck build. TPI was on my other Jeep for a few years with no trouble. timing is right on, fuel press about 38- 40, filter clean. threw a code for Knock sensor, replaced it, now no codes. Starts easy, runs great for 5-6 min. then loads up coughs sputters but idles fine. If I let it sit for a while starts right up, runs great again and then same problem..
gettin ready to start throwin wrenches....
