Just choose up a 97 Suburban. Countless issues, first thing I need to take care of is the blinking/on inspect engine light. P0308: cylinder 8 misfire. You deserve to really feeling it, particularly at idle. I"d say it"s a dead miss out on (as in, it feels like that cylinder is act nothing)...Anyway, man I to buy it off of states his mechanic walk a song up and it didn"t help, and also thinks the trouble is the valve adjustment.I"m walking to execute a compression test on Monday, to check out if the trouble really is mechanical. If it is, any kind of idea even if it is a misfire can be brought about by a valve mediate problem, and if so, I"ve never readjusted valves before... If compression is fine then the rules the end the valves, right, and also I should focus on fuel or spark.Thanks for any input!

MRRSM post it in mine thread indigenous yesterday re: stormy idle...http://easyautodiagnostics.com/gm/4.8L-5.3L-6.0L/how-to-troubleshoot-a-misfire-1Yes, yours is a small older, however except for yours no being coil-near-plug, the values are mainly the same - and, yes, once spark & fuel are ruled out, the conversation does rotate to points mechanical.If the does revolve out to be the valves, I"ll assumption: v they"re too loose, fairly than too tight. The course, yours can just it is in a loose plug wire, as mine turned out to be!

Valves space non-adjustable hydraulic. Normal suspects because that misfires in bespeak of probability and also expense:1. Dead coil/plug wire/spark plug2. Loosened spark plug3. Wiring come coil4. Fuel injector/wiring come it5. Loss of compression early to burnt valve, dead lifter, damaged rocker, swollen piston
