Question Please Help TCS Light and SES Light!!!!

Ok, after the Cam install and tunning, my car is turning the TCS light and the SES light on. The TCS light goes off and on randomly, the SES code says MAP Sensor problem. Could an issue with the MAP sensor cause the TCS to come on and off? I do not believe there is a problem with the MAP Sensor itself, I think it has something to do with tunning. I can e-mail my tune to you if you want to look it over and give some advice. From what I understand, if the MAF and the MAP peramitors do not match, it can throw MAP codes. Is this true? Can it also cause TCS issues too?

Your VE table is off from the new cam, and the speed density calculation is way out of whack. The MAF reading is compared to the speed density calculations (mostly based on MAF and TPS) as a sanity check, and the numbers aren't jiving to the PCM.

Yes it will cause your TCS to randomly turn on/off as well.

What are the codes being thrown ? Did you drill your TB, and if so to what size ?

Cheers,
