Stabilizer light, service trac stabilizer, check engine light on, engine power reduced. can turn car off when allthis happens and it runs fine for awhile then it will happen again. took it to the garage and they say it's the throttle body. what does it have to do with the trac stabilizer?
It's all tied together in the computer system . When you start to loose control the computer takes over reducing engine power , applying brakes etc... to bring vehicle back into control . The throttle body on your vehicle is computer controlled . electronic throttle control . the gas pedal has sensors , the throttle body has sensors an a electric motor . The lights came on because the computer disabled these systems .

These trucks have a drive by wire system,we seen a` lot with a broken ground wire on the rear of the drverside cyl head,this is hard to see just feel and give the wire a tug .If the wire is loose or broken the reduced engine power light will come on.

You have some kind of ECU problem. You will need to hook to the diagnostic port to find the problem. Your vehicle has gone into limp mode. This enables the vehicle to run, but at a diminished level until you can seek help for the problem. Do not continue to drive it this way as you may cause damage to the engine depending on the nature of the problem.

Please go to the crossfire injection forum to get some straight answers to the 82 corvette CFI system and how to troubleshoot it properly. There's a lot of misinformation given here, so much so, I don't know where to begin.
One thing is, the 82 corvette CFI does NOT have a MassAir Flow sensor system, it uses MAP and O2 mostly. The CTS sends a signal to the ECM telling it what the temp of the motor is and in turn the ECM controls the amount of fuel being dumped. On the older (orignal) CTS sensors, they have one wire and takes its ground from the threads. If any coorosion takes place, usually the CTS will report a cold engine and request lots of fuel.
To repair this issue, install one of the newer style CTS sensors that have two wires, one for signal and the other is ground.
Fuel pressure and vacuum leaks on any CFI motor play key roles. Set the FP to 14-15psi measured inbetween the TBs. The regulator is located on the rear TB and must be slightly moded to make it adjustable and can be done in a few minutes.

There is either a high or low circuit problem with the motor. The ecm, or called the computor, moniters the cuircuit for the motor.
The best thing to do is have the control motor checked and the ecm. One of them is bad.

po455 is Probable Cause[s]
1. Defective, loose or missing fuel cap
2. EVAP canister broke, hose cracked or not connected
3. Purge or vent solenoid defective
4 . Vacuum leak at engine po121 code po121 means Throttle Position Sensor/Switch A Circuit Range/Performance Problem . it is usually indicative of a faulty throttle position sensor or faulty wiring harness in the engine bay.
