The car has been running great. Daily driver with no codes, no stalling or poor miliage, etc.... Now suddenly this morning, it won't run.

It has a tough time starting, and when it does finally catch, the idle is surging around 300-400 rpms until it gives up. I can give it gas, and rev it up no problem, but as soon as I release throttle, it bogs down and dies again.

No codes, no warning lights. Good oil pressure. Good voltage check. Any ideas?? I'd appreciate ANY advise you guys could give. Thanks in advance.

Mods in sig, but they're several months old, and it was tuned by A&ACorvette up in L.A. so I don't think they're causing the problem.

 

Fuel pump possibly?

 

try and unplug the MAF and start it,and what he sais,check and see if you can hear the fuel pump prime when you put the key in the on position.

 

Thanks for the tips fellas. It started right up this morning.

It's probably going to wait until I'm late to the airport or something crazy before it does it again.

Cheers all.
