Motor has a miss

[hellyaitdrags]

I got a 1994 d21 with 2wd 3.0 v6. Motor has a miss and all the plugs have been replaced. Was wondering where to start looking. I have looked with a timing light but I don't know what im looking at. I set it on cylinder 1 and it looks like its not at 0deg. Don't know what its supposed to be at. any help is greatly appreciated!!!!

Could be a whole bunch of things makin it miss. A few are bad plugs ( which you fixed), bad fuel pump, bad distributor,or bad sensors like crank or MAF

Oh it could be the maf. I've had trouble with loose harness on that b4. Is there a way to test it?

Just see if a local auto shop has some for your vehicle in stock and if they will put one that's new on to see if that's the problem.

Do you happen to know of any maf upgrades available for this motor?

i don't think so just replacements. But i don't know for sure.
