I first changed out the plugs and noticed the problem. I installed NKG TR6 plugs stock number 4177 T R 6 V-Power Resistor Type, and noticed when the car was idleing it wants to idle rough and die. I then installed 39# Ford Racing injectors and a new tune from Nelson Performance, I told Nelson Perf. that it had TR6's gapped at .030

The electrode on the plugs is white, and it's also throwing a trouble code, Bank 1 & 2 Too rich.

Any ideas?

 

Could be a tune issue if you have eliminated the plugs/wires as a fault, checked for cracked porcelain, loose wires, etc.

 

I've pulled 4 out of 8 plugs and all are white. I'm thinking it's a tune issue, but I had the problem before the new tune.

 

Was this a mail tune or a dyno tune?

 

Mail order.

 

Can't mail order a tune for a turbo car.

 

Yeah, don't get a Nelson tune. This doesn't just apply to mail order, as he does the same thing for in person tunes.
