98 Supercharged Cobra Stalling issues

[1AestheticCobra]

Hey guys,

so picked my car up from the tuner around January. I drove it home 2 hours and it was fine. Drove it a few times before it started stalling at stops after warm start ups. Also warm start ups are tougher. Went to start the car last night and heard a soft pop along start up and now it won’t idle at all unless I’m on the gas..

I’ve been in touch with the tuner and have been talking to him since, but at this point I’m just trying to figure out if it’s something I can take care of since it can’t drive because of how rough it runs. It’d be difficult for me to get it over there. I’ve checked the tps sensor, the IAC should be good, and the alternator was testing and was reading at about 13.4v. Any other ideas?

Thanks in advance.

Kinda impossible to guess, would need to see a data log from the tune or when it was fine, and a recent one.
Literally could be anything.
Towing it back to the tuner may be the best option.

Good luck though!!

The pop the would concern me. Are all the vacuum lines connected?

It concerns me a little as well and yes they are from what I can tell. It was kind of a muffled pop though. Not insanely loud.

Easiest way to diagnose it is with a moates quarterhorse. You can see exactly what its doing.
