weird power loss kinda problem ok here is the deal, a few months ago my car had problems with a few lose wires and a few plugs not firing good. well i put it all back right and then when i ran it for a week i check the plugs and 2 looked like they were firing weak, the ones that werent pluged in right. when i fire up my car sometimes it doenst sound like its firing up solidly, its hard to explain but it just sounds weird. could have a weak plug by any chance? and what else should i check out for this kinda problem, sometimes the car just feels weird and inconsistent. might feel strong one time and not hte next. i figured plugs woudl be a good start seeing my tune had issues of being too lean. so i was gonna do plugs and try and make sure the tune is still where it needs to be. any other ideas?

what signs do i have to look for for a bad MAF sensor? my tunes seem to have to have a lot of WOT fuel put in. so any tips on how to check this out. i figure that and plugs could be the only real issue here, and getting the tune corrected if it changed

only reason im curious about the MAF is becasue my tuner said he had to add a lot of WOT fuel to make my air fuel come up to a good number. also i was getting pinging but the air fuel was showing low. when he gave me the normal WOT fuel in my car he said he uses in most fbodies it ran about 800-825mV on the o2's now its runnin good at 900mV. could it just be my car is different with the set up i am running? casue i hope its not messed up. just let me know. im gonna try plugs becasue i was having this kind of problem with the stock ones and when i replaced them it seemed to fire a lot better. thanks
