96 Check Engine light on

bmwgolfguy · #1 09-13-2006, 08:44 PM

I have a 96 LeSabre and the Check Engine light is on. It has about 101k on it and I am the second or third owner. Other than the light, there are no visible or audible problems that I am aware of. I called a local mechanic who has worked on this car in the past and they want $85 just to run the codes & diagnose the problem. I have put more money than I want to in this car already having recently done the plenum and upper and lower gaskets. Any thoughts would be appreciated.

Take it to Autozone or Advance and let them read the code for free.

Thanks. I will give that a try.

I took it to Autozone and the code came up P0442 which apparantly has somthing to do with the EVAP system. One of the suggested fixes for that code is a new gas cap. I don't think that is the problem. I think it is probably one of the hose/tubes for that system, but I am not a mechanic. Maybe when they fixed the gaskets they "pinched" a well worn hose that needed replacement anyhow. My son and I plan to dig around the engine hoses this weekend and look for leaks that we can see.

Just a thought.
There may be a hose in the wrong place.
I understand that emission system is a gas vaper purge maybe problem is control valve wires. The system waits till the engine has been running for a while and purges the vapors back into the intake.

Not sure the PCM knows theres an actual hose leak, just a control line off.
Gas cap is a one way gas vapor valve. I suck on em' working. (not good but works)

Good luck

Thanks. I will take a look and see if I can spot a hose problem.

I had problems with my engine check light coming on and off also. It was the upper manifold problem. I had this fixed then the MAP sensor went out on me and this made the light come on also.

Am holding out to have this fixed. Now I have a water pump leaking and have to get this fixed or I won't have an engine.
