Damn Boomer!! I thought I made a post about my car and didn't know it! LOL I'm doing the same thing right now.
I just checked my ECU thanks to NOSTRODOMAS' advice, and sho nuff...code 0302..."EGR control valve does not operate" Gotta check for prices now.
Do we have two EGR valves? I'm looking at the diagram (from the Haynes manual I think) and it shows an EGR valve at the end of the throttle body arm where the intake arm starts, and an EGR valve & EVAP canister either on the throttle body itself or just underneath it. If there are two, then how can we tell which one is jacked up? I will go look under the hood and double check.
No, dude. that's fine. Thanx. Yesterday, I never turned the car back on after I reset the ECU. This morning, (Had to work) just hopped in and drove. No check engine light. Just now after work I tried to run my ass to the Smog Station before it came back on LOL!! But I got dinged for the Ebay air filter. So tomorrow I will run to the junk yard to get a stock one, and try to do what you suggested with the hoses. I hope it will work. My idle is a little off. I advanced it a little so the car won't die at intersections. But we'll see. I should change the damn oil too.
