If im cruising in the highway at around 1500rpm my check engine light comes on but if I let go of the gas and or it drops under 1300ish it goes off.

Will this cause me to fail the new roller style smog tests?

I know I need to get a code reader hooked up, I was just hoping somoene had a easy fix.

Yeah, could cause you to fail. It could be EGR. That's right about the RPM the EGR functions.

I have a code reader if you want to use it. Let me know. It should have a stored code in there.

Give me a call if you still have my cell # or PM me.

Sean.

Yeah that sounds like an EGR to me too. That would be the first thing i look itno.

Sean can you PM your number, are you busy this weekend?
Maybe we can try to take a look at it then.
I really want to get it smogged ASAP.

Rest of the guys thank you for the help

EGR or maybe EGR Valve Position Sensor. Good luck.

Before I replaced the EVP, the Check Engine light would flash on and off. It seemed to flash on when I was accelerating (whether or not WOT or light acceleration). It would go off as soon as I lifted foot from pedal. I suspected it was not the EGR as it had been recently replaced. In any case, if you don't have a code scanner, get one from a friend or Autozone (pretty cheap), run the codes and that should help you out.

BTW, the EVP is located right behind the EGR.

Hey, glad to hear it passed. Now it's time to yank that motor!

Did you go to the same place I went last time? What kind of intake did they ask that you had?

Sean
