No. I have seen in the past MSD7's eat up ignitors and ICM's. If it was fine on the dyno it just means that your disrtibutor went bad after or you are having weird problems with your aftermarket ignition. The reason I made that comment about not messing with aftermarket ignitions earlier unless it was needed was because now you are complicating your issue by adding in another unknown variable to test.

How old are your plug wires? Are the OEM or NGK? What plugs are you using?
Do you have a Helms manual? Do You have a digital multimeter?

I would first test the Ignitor and ICM. If they fall withing spec then disconnect the MSD7, tighten the plug gap and convert to stock ignition.

If this fails then Run a known good distributor to see if your bearing are trashed in your distributor. If you are going to buy a distributor then the Moroso is fine.

 

Erik, aren't those plugs a bit on the cold side?, I'd try some BKR7E with .028-.030 gap.

Also, did you check that coil wire tower spacer? You can feel with your fingers to see if it moves, or not.

 

Those plugs aren't too cold, and the car is going lean, causing the misfire. Something changed from the dyno, either a fuel pressure problem or a bad sensor somewhere...

 

... damn , but he changed most of the fuel components. Erik you need to hook up that fuel pressure gauge and see if their is a clog in one of your lines.

Have the injectors been tested?

 

No I dont have anyway to test the injectors. Those are brand new too. Imma try and hook up my oil pressure to the fuel and watch that.

So what else fuel related should I check before I bring it to you Tony?

 

by the way it's missing now at about 4.5k under half throttle (normal driving)

 

Erik, they're Precision injectors right and what size? Although they are new there have been a few cases where the injectors were bad from Precision. That could be one possibility. Maybe I missed it above, but what gas are you on and how long has it been in your tank?

 

yeah you did miss it..hahaha. I been on pump while this is happening and its new gas

 

I hooked up a gauge to read fuel pressure inside the car...it isnt dropping off at all. Matter fact once I jump on it it goes to a reading and holds that same pressure. Doesnt go up with boost or down when it starts to mis-fire. Im thinking bad injectors maybe. Should I have them tested here in town before making the trip to Dallas?
