Ok... most of you now know my motor and car. It fires on the #2 all the time, but it hits #1 #3 and #4 every once in a while. Bad ecu? It was chipped by xenocron. IT gets fuel and all but just the spark problem now. Maybe this would explain why it didnt rev that well.

Everything else on your ignition system checked out good? Did this just start happening when you got the chipped ECU?

simple have solid check engine light just a solid red yes ecu is an issue if not than its wiring/sensors

The only CEL is for the IAT. I put new plug wires in and all and same results. Could this be because my dizzy is only held by the top mount? It is solid and all. When i take the chip out, it is a solid red. But when i put it back into the socket it flashes 10 times, which is the IAT. Would any wiring from the MPFI swap be the problem? Anyone have a MPFI swap harness for sale?

ecu is fine

88dx

get rid of the IAT cell it can cause a solid cel,

But it still doesnt change the fact it wont fire on 3 cyl. Any other ideas?

Did you try changing out the distributor? It may be a bad dizzy.
