hello! Started up my 96 1500 to go home from work and it sounded a little 'off'. Got it on the road and yep, she has a miss. A steady miss. One cylinder aint firen' at all. I cleaned the throttle body a few weeks ago so my guess is that some gunk clogged up one of the injectors? Or fouled plug maybe? Plug wires look ok. Any advice? If it is an injector do I have to remove it to clean it? thanks allot!!
