'97 4.3 S10 bogging problem....FPR was bad, and inj. o-rings
Ok, ever since I plugged in the plug on the CTS (coolant temp sensor) that was broken off, the car runs like total ***. No CEL anymore, tranny shifts great. It does NOT stutter/bog when taking off normally, but when attempting to WOT, or passing/ going over 2500-3000 rpm 3/4 throttle, it will bog and stutter, no backfiring, no flashing CEL. I just did a tune up on it today, but it did it before the tune up, after I plugged the CTS in. Unplugged it runs great but the CEL is on. So plugs, wires, cap, rotor, air filter are all ruled out. Anyone have a clue what it could be? I got good oil pressure, good battery voltage, idles perfect, etc.
