I am new to this site and threads so please bear with me. I have a 1984 crossfire and when it gets up to temp it starts dying if you give it any gas backfires and dies. It will restart every time but same problem when you try to give it gas. Also, when the car is started and it is cold it runs great, it only starts its problem after 20 to 25 miles or so. Does anyone know what is going on with this car? I sprayed wd-40 around the intake and it never idles up so I dont think its sucking air. Also this is my first vette. I have had it a year and it started this about 2 weeks ago. Thanks for any help I can get

CrossFires Now Popular?

In the past 3-4 years very few SmokinVette members had '84 CrossFires but it seems all of a sudden they're popping up often. Same as the '82 CrossFires because lately they have been popping up often too. So did the CrossFires suddenly become popular?

The CrossFires are a good reliable system that just needs an '85 fuel pump and more pressure to run with the earlier Tuned Ports and I'll be very happy to help anyone who is having CrossFire issues. Just e-mail me at [email protected]

When the TH700R4 was introduced the intake systems had to be changed to reflect the port velocity of engines spinning 1500 rpm at cruising speeds.

I love this car alot. It sounds like I need to get an 85 fuel pump but this car is amazine. Its my first vette and I am sure I will keep it for years to come. It does have a larger radiator to help with the cooling. I also changed the a/c to the 134a and new seat covers. plus I painted it Ferrari (paint code 322) red

backfiring is usually a timing issue, but it could also be a low fuel pressure problem
