95 SL1 check engine light only when hot
ok so the car had roling idle up and down then it would stall. No check engine light but pulled codes 32-egr system fault, and 45-system too rich. Well pulled the egr valve out and there was a pool of fuel in the intake manifold. Well checked and found the fuel pressure regulator was leaking and pumpin fuel through the vacuum hose into the intake. Well replaced the FPR and cleaned the carbon off the egr valve and started it up and blasted all the fuel out and carbon out on a test drive. Replaced the front o2 sensor and it runs 10 times better. Anyway, now the car runs great but the check engine light comes on when the car is warm. When its cold its off but when the cars warmed up the light comes on. I heard theese got some wiring issues with them.

Re: 95 SL1 check engine light only when hot
Could be thermostat, ECTS, something temp related. But first things first, get the codes and post them so we will know for sure.

Re: 95 SL1 check engine light only when hot
OK, the code is 32 (egr system malfunction). Cant really test the egr valve because its electronic and it seems like the intake ports are clean. Well the car drives fine and the MPG's are fine.
