It been a war getting all the bugs worked out of my so called buget build LOL.

Now I think I have a Bad EGR valve the car was running great but all a sudden it started running very poorly and some times just die.

I became hard to start idel ruf or just die.

Lack of bottem end power I think the EGR go bad and it not that old 1000 miles on it.

And the MPG are not that great.

I checked for vacume leaks so far cant find any retighen all intake bolts everything is tight.
Rechecked the timming still good.

Any other ideas before I pull the Plenum off to change the EGR valve.

It might not be the EGR after all.

One of the members from anouther Fourms told me unplug the EST and see if runs better It did then he told me to redo the timming so far it running better.

I move it up to 6 adv and started to run worse.

So I moved it back to 4 Adv.

The motor seems to step up to 2000 RPM then flatens out it not stepping up anymore it stays flat to red line.

It not pulling hard at all.

Yes, it has to be unplugged to set timing initially. Glad it's running better! Let us know if it doesn't hold for some reason.

Merry Christmas!

I just did anouther code check I getting code 42.

No engine check light like last time I got a code 42.

Last time it was a bad wire.

I will pull the distribtor back out after the car cools down.
