4L60E Transmission TCC Shudder? No, Misfire!

4L60E Transmission TCC Shudder? No, Misfire!

This vehicle here is a 2003 Chevy S-10 with a 4.3L engine. It has a new ignition coil, distribuitor cap, rotor, spark plug wires, spark plugs, fuel pump and fuel pressure regulator. But it still has a misfire on cylinder 1,3 and 4. I could have done more testing. I could have scope my secondary ignition system to see where it would have taken us. Remember, I’m a Tranny guy, I need to know if its my Tranny or the Engine causing my problem. With all the ignition items installed on this vehicle, I sould have done some scope testing, I cuold have an ignition module or worn bushings on the distribuitor that are not working right. So the customer was informed about this, I let him know that his mechanic that did all his work for him to check these items before taking the engine back apart. To me, at first, seemed like injector spray pattern, which in this case, after the injector clean did not do a major change. It helped some, but did not fix his misfires. so there we have it, please subscribe, rate it, and share this video. Also click on my name above and watch the rest of my videos. Thanks for watching.
