cobra problems

[TRPLBLAKSVT]

Whats goin on fellas? I have a 97 cobra vert with all the major bolt-ons and ive been havin some probs. Ill fire the car up n it'll run just fine until it gets up to temp then itll start runnin like ****. It will start missin and just run rough, if I kill the car and let it cool for a few ill try and fire it up, it will fire and immediatly start missin and die even gining it gas, almost seems like its loosin fuel pressure along with somethin in the ignition, the problems almost exclusivly happin when the car is up to temp, but its not overheating.. can anyone one help??

Could be a number of things. You need to test fuel pressure. Also, is it throwing any misfire codes? If so then you prolly have a coil pack going out. Check your plugs too and see how well/bad they are burning.

Ah, clogged fuel filter is what I would first check.
Then check the fuel pressure regulator. Do you have an off road h-pipe?
Also the O2s may be dying. Fuel pump is another thing tio check. You need a fuel pressure gauge.
