I just took my car out of the garage for the first time this year over Easter weekend. It usually stays in the garage from October/November until April or so. Over the course of the winter I start and run the car for about 15 minutes or so to circulate fluids and get it up to operating temps.
After bringing the car out last weekend I had a problem where the car would start up and then die in about 15 seconds or so. The only way to keep it running was to rev the RPM up about 4k for a few minutes and then I could drive it. As long as I was driving, no problem but if I shut the car off I'd have to do the whole thing over again.
After I got home I hooked up my Predator tuner and increased the idle RPM up to about 900 RPM and reloaded my tune. This seemed to help the car quite a lot. Now the car will start up and the idle will go up to about where I set it (RPM wise), then dip down again to around 650 or so, then come back up to 900 or 950 and the car will idle fine. Every once in a while while stopped at a stop sign or just as I'm stopping at a light the idle will drop down and the car will stumble some and come back up also.
I've checked under the hood for any loose connections.
Checked for cracked hoses.
Checked for vacuum leaks, using carb cleaner.
Gotten a new tank of fresh gas, twice.
**Edit** Also cleaned air filter and MAF sensor.
All seems ok there.
The car has FRPP hotrod cams, FRPP shorty headers, FRPP CAI (the one that uses the stock intake tube) and a custom tune.
Is there anything I could log in the tuner to help diagnose the issue?
The car isn't throwing any other codes and otherwise behaves fine.
