The 452 error started last winter when a Chunk of asphalt kicked up and streached the fuel line and tore the evap line. I replaced the fuel line and bridged the evap line. I keep saying I am looking for a leak because of this. I have already replaced the EVAP selonoid because when the hoses pulled it broke the unit off of the bracket. I also double checked (and triple checked) the wires in the area of the selonoid. I droped the gas tank and could not see any signs of damage from the pull. Where is the other sensor or wiring harness I should replace/check.
Today I pulled the EGR valve and attempted to clean it. It did not seem to stick but it was carboned up a lot. The car is still surging so I may grab one from a junk yard to see if ireplacing it makes a differance.
I am about ready to take it to a shop and let someone else give it a shot. With 170k on the car and all the other minor problems added in, I just cant justify droping a lot of money to fix it. If it were not for NJ inspection I would just drive it utnil it dies.
Thanks Aain for the info.
