Since h/c, car idles like crap and now a code
A couple of weeks ago, I had the pp ls6 heads and the tsp 231/237 installed. The car was dynotuned by APE. Even at the initial start when I picked up the car, it would start, idle way down, hellasious lope, then idle would pick up a bit and it would seem to find itself at around 900 rpm. Took the cats off last weeks replace with racepipes and o2sims. Since the day I picked the car up, about 4 or 5 times your driving along in 4th or 5th and the car just stumbles like for a split second it fires on 7 cylinders. Today, while driving it did just that and then the SES light came on. Got home hooked up autotap and their were 5 codes, all the same, P0101 Mass Air Flow Sensor Peformance. What is this problem and what do I need to do to fix it?

I recently got the TSP 231/237 installed to and the other day just driving down the road I got a MAF code to. I cleared it and it hasn't came back since(couple of days).

When you first start it, it's a bitch to keep it running. Then when driving down the road, it like falls on it's face for just a second, but otherwise, it bucks and jumps, and now this code?

How's the MAF look? Maybe it needs a cleaning. Twice now I've noticed unusual, crappy idle. Both times, the problem went away after cleaning the MAF. I used some electrical contact cleaner, from radio shack, it comes in a small aerosol can with a plastic bristle brush.
good luck!

I think it is safe to say that they over-tuned your MAF tables to compensate for your cam. Just my opinion though. What do your LTRIMS look like?

I found your problem. P0101 shows up when:
The MAF frequency is 50% different from the speed density calculation for at least 5 seconds.
What this means to me:
They messed up your tune. Check your MAF for sure though.
