I am having trouble with my car missing. I was wondering what the major places to find the issue would be??? I plan on checking all the plugs, wires and dis cap tommorow. I was thinking it could also be an injector (Just a hunch is all nothing to back that up), but I don't know how to check them. Also I am getting a loud popping sound as I cycle up through the rpm range (Thinking unburnt fuel in the cats). Sometimes it happens 3 times between gear changes, and sometimes not at all. If I stay above 2k RMP's then I don't hear it at all.


Thanks for any help in advance.

tune up probably wouldnt hurt. also check your timing,and check for vacuum leaks.

yea i was going to say your timing aswell, cause when i took my dizzy out when i replaced my intake manifold it was off and it was popping and ****, once i fixxed the timing it was all good

It really isn't a pinging issue (I am assuming that is what you are reffering to), more of a loud popping like someone smacking a 5 gallon bucket. I just put new wires, plugs, cap and rotor onher about 6 months ago along with adjusting the timing then as well (I don't have a timing light so I just bumped up the timing little by little until I heard pinging and then backed her off a little). I am going to check the wires and plugs tommorow (Murphy's law), but could the timing get back off again all of a sudden???

did u tighten the bolt that holds the dizzy in place?

The popping sound your hearing sounds like a backfire through the intake? You may want to get a timing light and check it ,as you said many things can cause this but borrowing a timing light is going to be the cheapest thing to do atm.

I tighned the bolt down pretty good, but I am going to try and borrowa light from one of the auto parts stores in the next couple days (I have to go out of town tommorow). Thanks for all the help so far
