I installed my Delteq last week car ran better then ever. But on Friday I thought I could feel a slight miss. Saturday I went to start the car and it turn over but would not crank. I pop the hood and just pushed on all the connectors. Got back in and it took a few times but she started. I drove the car to work after work it started right up. I drove a little over 100 miles one way and the more I drove the more I notice the miss. I stopped at a shopping mall check Plug wire and other connections and she still had the miss. I went in and got my shopping done. She cranked right up and drove fine until about 30 minutes then the miss start out slight and just got worse. I been check thing and cannot fine anything. No codes and after it sit for a while it fine and it fine on short trips, but after 30 minutes it starts miss and just get worse.

Anyone with any ideals

Thanks,
Mark

 

How old is the opti that you're running the Delteq of?

-B

 

Sorry I had a new GM one installed 2 months before the delteq. I also should say I made my own plug wires from a Universal set of 8.5 MM because I ran the over the top. because the headers made it easier

 

Not sure if anyone cares but think the problem seems to have been loose header bolts. Not sure why. but as I was checking every thing I figured I check my new headers because they have only been on the car a week. Yes they were loose some hand turning loose. After that I ran the car for over an hour and she runs great. So anyway we will see.

 

Thanks for the update. I'll keep that in mind when it's time to install mine in a few wks.
