Ya its egr voltage high and exhausted pressure to high. I pulled the cats of and washed them In soapy water. Stuff did come out of them. Don't know if it will actually help or not.You are getting a code for the EGR?
What is the code
Did you clear the code and then it comes back?
The ecm uses the speed sensor to calculate fuel economy, 3-4 shift, tcc lockup for the auto trans and some other stuff I'm forgetting at the moment. Have you removed the egr valve to inspect it for carbon buildup?Well thats because I need a longer cable. Dose the speed sensor have anything to to with the egr? Do 1st gens actually need them for the computer?
But, only if you actually move to one of those regions....After your smog is sorted this time, consider changing reg details for this vehicle to neighboring amador county or one of the other program area 3 regions that are so close to Sacramento.
