Give Pete a call at Delteq and tell him of your problems if you haven't already. He is trying to figure something out with my car as we speak.

Re: Stumbling, Spittering, Backfiring...(Delteq)

UGGGGG,
I think I can tell you what the problem is and niether of us want to here it. I had a crazy miss at 4K and it ended up being the opti. I swaped the opti last week end and it solved the 4K miss problem but now my car runs like crap for about 1-2 min in the morning. With the old opti I did not have the problems in the morning, it has only started after I did the sawp. I think I am going to just live with the problem for now because that job sucks but I am going to give Pete a call.

Re: Stumbling, Spittering, Backfiring...(Delteq)

Did you change the plugs and wires before your did the install? If so I would look them over. Because it sounds like your car is only doing this in open loop mode. Where it runs on the stock a/f tables. Maybe they arent cutting it. And once the pcm goes closed loop, it fixes the issue.

This is a guess. But honestly is your best shot, and will cost you no money to check. Looking at your scanmaster, do you notice anything out of the ordinary? Are you 100% that you inspected all the parts you moved/tampered with durring the install?

I have inspected everything. The opti was perfectly fine before the install. I als changed the plugs but went with the exact same type.

I changed out PCM's tonight and that had no affect on the way it ran either so it can't be in the tune of mine. Now on to more tests....

I am still fighting this problem. I might put the original ignition system back on it soon and get rid of the Delteq.
