HELP!! Can't go over 3k RPM

[Ronson87]

Hey guys, recently had to replace alternator (shocker on an 04 Cobra) and the radiator (after it popped and covered my engine bay). Since those were replaced, once the car warms up completely to running temp it won't go over 3000 RPM and the AFR reads lean. If I start it up I can go around making full WOT pulls with no issue, but once up to temp, it won't work. Please someone's got the answer, I know it!

Have you checked your intercooler to see if fluid is flowing.

The intercooler or the radiator? I haven't touched the intercooler.

The intercooler reservoir as stated. If your pump is dead the fluid will heat until it pukes.

And that will stop the car from receiving fuel and not going above 3000RPM?

Are you having fuel issues or guessing?

Super high IAT2 temps can have undesirable effects. It's a simple check to rule out your pump.

I will check the pump for sure, anything at this point to get it running right. But my AFR it dropping to full lean and the tach won't go above 3k.

That would be useful info to put in your original post. You might have a dead pump or have had a line pop off in the tank. Maybe a clogged filter.

Also stop going WOT until you find the issue. Hope you haven't damaged anything already.

Up till it reaches running temp it runs perfect, AFR reads great.
