Misfire

[Markus Escamilla]

So i have a misfire...i change my cap, rotor, plugs, ignition coil, ignition control module, i even replaced my lower intake manifold gasket and timed my distributor. Then after all that i still had a misfire. What more could it be...a timing chain!?

Clean your mass air flow sensor properly....my 97 was still misfiring and that resolved it.

If that doesn't help for some reason....check your fuel pressure, fuel filter, fuel pump...etc. Engine fuel mix may be off by another cause.

I changed my fuel filter a few weeks back...i forgot to mention that but i will check the fuel mix, pressure and pump

So after all the trouble I finally found out it was a timing chain
