Question about Chevrolet Cars & Trucks
I have a 1995 Chevy Lumina and the check engine light has been coming on about 20 minutes after I start driving. If I turn the car off and turn it back on it's gone for another 20 minutes. The codes it spit out were 34 and 51. What do I need to get repaired, and about how much should it cost me?
Code 34 is for the MAP sensor voltage being low which means the sensor is unplugged or faulty. Code 51 is for a problem with the memory chip inside the computer.
If the engine computer is failing it could set the code 34 even if nothing is wrong with the MAP sensor.
The computer and MAP sensor would need to be checked out.

SOURCE: check engine light
you need to go to an electronic specialist or you can buy one of the scanners that clears the codes for you from advanced auto or autozone or some place like that.

P1361 TDC Sensor Intermittent Interruption (I got this from Engine-Light-Help.com)
TDC should mean Top Dead Center.
It is the sensor that tells the computer the #1 cylinder piston is at the very top. And therefore, fires the spark plug.
Since the maintenance done above, I believe the the timing marks for the timing belt is not lined up properly. Being off by one tooth will cause this problem.

With these computers, anytime your check engine light comes on and than you replace the part, the computer has to be reset with handheld scanner/computer.
So even with a new part, the computer still has to be electronically reset.
Even if there are no codes. You won't have codes because the part is new, but the engine light will remain on until it is reset.
If you have all new parts, no codes, and had the system reset. It could be a problem with the computer itself and will have to be put on a diagnostic computer for further testing.
