I have a 97 corvette , the check engine light was on so I took to dealership, they replace 3 oxygen sensors, picked up the light came back on. At a lost end. These are the codes...


You can look up the error codes on http://www.obd-codes.com.
Because the error codes indicate heater circuit failure.
P0135 and P0155 mean the heater circuits for the front oxygen sensors are not working properly. You need to check the fuse.
#15 under the hood I think.
If that is OK, make sure the exhaust system is grounded. I believe the ground strap is on the back of the cylinder head - right side.

It would be rare that both O2 sensors died again, that quickly. I suspect the dealer didn't really do any diagnostics and just replaced parts (cheap option at least for them).

I have loss of performance power and the service


one of the computer sensors are probably bad if you have a code scanner see what codes are stored if you don't have one now's the time to buy one they all work the cheaper ones just tell you the codes ( 49.99 59.99 ) then you have to look them up in a booklet that comes with it the more expensive ones ( 89.99 and up ) will tell you the codes and tell you what they mean. there is a new one on the market that will give you the codes and give you the most popular fixes for the code right from the scanner . hope this helps

I have a 1999 corvette showing trouble codes C1790 H, and B2606 HC can you help identify these codes


c1790 H ride control switch, the "H" indicates it has occurred at some point but is not present now. The H stands for history

b2606 HC is seat rear vertical position sensor failure. This code always appears as a history code. If this condition is current, your seat memory won't function.

My 2000 corvette had a recall on the sterring column lock and was repaired. The past weekend the sterring wheel did not . lock up but the fuel system shut down DIC indicated "service steering lock" What's...


I would irately call the dealer and have him send a mechanic out to fix your car where it sits. If he has to tow it in, have them use a car hauler. It would not be unreasonable to expect a decent loaner and they can add it to the recall charge to the company.

1986 chevy corvette service engine light


the light can be reset by disconnecting the battery for a few minutes, but the light is telling you there is a problem in the electronic controls of the engine, until that problem is fixed the light will continue to come on. Here is how u test the system for the trouble codes that are stored whenever the check engine light comes on. Go to the link for instructions on how to retrieve codes.

Fan won't shut off-service ride & service engine soon on


Buy a scanner or go to Autozone and have them pull the codes out. get back to me with the codes and I'll figure it out for you.
But the fan could be the relay or the coolant temperature sensor and ECU that controls the circuit. Have the coolant , hoses and thermostat been changed lately. Start with those things.
Get the shop manual and test the coolant temperature sensor,relay and ECU. These are simple checks usually a visual inspectionor a little probing with a Digital Voltmeter will solve the problem.
