ran 1st through 3rd at full acceleration and when i let off, RPM's cut to 0, power steering stopped, and the dash lights all lit up. turned car off and ran normal, tried again and did same thing. Have tuned HKS supercharger/hks exhaust... lojack... only things i figure would matter. what the heck is up?!?!

 

Clean your MAF and throttle body.

 

I remember I had the same issue with my TN setup. I like to say it was an air leak somewhere but it's been so long ago.

 

If cleaning didnt work, could be the camshaft sensor

 

I had this same problem before, no CEl for it either. turned out to be a common problem on the G/Z which is bad TPS. had to replace the throttle body to fix it but its been fine ever since.

 

What you mean by tps the throttle body itself was the problem? Or the sensor by the accelerator pedal

 

I currently have the same problem with the turbo kit where the leak was?
