Ignition problems......Grrrr!

[Raffaelli]

So lately my 94 has been having problems getting spark to the plugs.

First started off a few months ago (after I put the heads/headers on) (and new autozone wires). It would start to drop cylinders and miss a bit in the hi rpms under acceleration. Wierd thing is the tach would jump crazy when it would do it sometimes.

I know its partly/mostly the wires, (I have new motocrafts in the box waiting for it). But the tach jumping is a wierd one.

Now driving around today normally it all of the sudden burped, then died. Tried to restart it, but wasnt hitting a lick.

I had injector pulse (yea I carry a noid light on me), but no spark @ the coil. Had power @ the coil and it started up instantly after waiting a bout 5-10 mins.

Driving it home tonight it died twice; waited a couple minutes and it fired up fine.

Im REALLY leaning twards the ignition module. You guys agree? And its under the airbox, right?

Thanks for any input.

i agree i think you can get it tested

sounds like the module to me. Easiest way to test it is to check to see if you are getting pulsed power at your coil when it dosent start. if it does pulse and still dosent run then its the coil. but if no power to the coil then its most definitly your issue. not completly uncommon either. good luck

Could be module but I'm leaning more towards the dizzy

same symptoms I had when my dizzy crapped out.
This year I had a prob with the motor cutting out at hi RPM's, gave it a fresh tune up and replaced the coil and the prob went away.
I have 190,000+ on my oem ICM.

+1 on the dizzy

Well, today I got a new module andcoil and the problem is FIXED!!!! ccasion14:

Runs better than ever. It doesnt miss a lick right up till it bounces off the limiter changing gears.

Thanks again for any/all input. Im just glad it wasnt the dizzy.
