car missing randomly?

MuscleInc1320 · Nov 21, 2007

just like the subject says.....my 94 gt randomly will start bogging when i set on it and its idle will be a little off. kinda like it is missing or not getting enough fuel. then all of a sudden it will go away. it doesnt happen all that often but it is just something that bothers me. my bolt on are listed in the sig.....but i was wondering if u guys had any idea as to what may be causing this.

How long has it been since you did a full tune up? Cap rotor plugs filters oil?

That description is pretty vague as it could be a lot of things.
But I'd check things in this order:

Disconnect that MSD box for a while and see if it goes away
Distibutor cap
Plug wires (do the dark garage test and see if you can see any of them failing)
Fuel filter (BTW, is your fuel pump the original one?)

its been about a year sense i done a tune up and yea its still the factory fuel pump but the car only has 86 thousand on it. its not bad gas cuz its been giving me this problem for awhile now. i have thinking that maybe it just needs a tune up and maybe a good dyno tune it would fix the problem........ but then again it only bogs down randomly not all the time. do u think the ecu is just having a hard time adjusting to my bolt ons? i kno that the 94s have screwed up computers.
