i did a quick search and didnt seen anything right off the bat, so my aologies if this has already been discussed.
got a 98 2wd with a 2.5. over the winter i started getting EGR codes 0401 and 0402. i put on a new vacuum solenoid as i though i properly troubleshot that part, but i still get codes. took the EGR off and cleaned it, verified it operated with a hand pump and threw it back on, still get the codes. verified none of the hoses leak, so i am down to the DFPE sensor that i am going to try to put a meter on and actuate the vavle while running and see what happens....any more input is welcome.
secondonly and most recently i have a 1450 EVAP unable to purge or something. i had this last summer and it would come and go. now its back and pissing me off. is there a quick way to troubleshoot this crap? i hate not being able to see all the lines, but is this typically something as silly as a gas cap gone bad?
anyhow, i just spent the last 3 hours getting nowhere, so any help is appreciated.
