Question about 1996 Chevrolet Suburban
I recently did a tune up on my 96 GMC sierra with a 5.7 vortec engine. I replaced the spark plugs and wires. The truck was running fine before but now it has a random misfire. The diagnostic I did gave me a P0300 code for a random misfire and something to do with my mass air flow censor being faulty. I replaced the censor and erased the codes on my computer as well as resetting it and it still runs like ****. Could I have a bad distributor or a bad connection somewhere? Why would my engine be running like this now and not doing it before? Anyone have a suggestion?
Couple of things, did you actually gap the plugs yourselfor did you go on the assumption that they are pre gapped ? are the lead wires all in the correct firing order ? Is it possible a vacuum line got dis-connected ? I would also check the cap and the rotor.
