a little history on the car, car is a 90LX 5.0, bought by my father in 1992 with 8K miles on it, when bought it had 355 gears, intake silencer removed but included, underdrive pulleys, and a Hurst shifter. I bought it from my father in 2005, added an X pipe, 70mm FR T-body, and EGR spacer, also added an SN95 MAF, correct number to work with ECU.
The car has a soft CEL, and according to my father has always had it, so that eliminates my mods affecting it. The CEL will illuminate inder part throttle at varying speeds, no rhyme or reason. My father said it has always done this and his dealer attributes it to the intake silencer being removed. Being that there are no codes and the car was rarely driven my father accepted that answer. I on the other hand won't It has me really puzzled, the car is in TOP condition, always maintained, always gargaged, always well cared for. I have tried pulling codes several times but have never found any other than the standard 11 for all is well, and the car runs AWESOME, it just annoys me that the CEL illuminates from time to time. It is my fun/weekend car so I don't get in it much, but I was in it today and decided to try to solve this again. I'm leaning towards the 02 sensors maybe but that really is just a guess. I guess I could try to put the intake silencer back in but I seriously doubt that is it since people have been running cone filters on these things with no CEL's. Any input appreciated.
