Got the flashing CEL again last night, this time it gave me pending codes. It's the same P0300 301 302. So swapping the coil packs did not change the codes. I'll try some new spark plugs and see what happens.

 

AC Delco Iridium , spark plugs!

 

Also make sure to check the gap, while it's been said they are pregapped I've found that the gap was more. If you still have a problem try closing up the gap, try .025-.026 and see if that helps.

 

If you touch the whisker it will break!

 

Forgot to mention that.... yes it will, you have to be very gentile.

Thanks donbrew.

 

Well, I'm not Jewish, so I am gentile.

 

I'm not Jewish, but I am ..ah.. well, you know, I was born in the 50's in a military hospital, it was automatic. So I'm almost a member of the tribe, but still gentile.

 

Gotta love spell check some times

 

Oye voy!

 

After reconfiguring my PVC system to phase 3 of testing, I was on my way to the hardware store when I realized I had forgotten to hook up the MAF sensor wiring. Pulled over and reconnected it, had driven about half a block.

1 or 2 more key cycles (only a mile or 2) I got a solid CEL, P0301 misfire. So I don't know if it's from driving with the MAF disconnected or if it is injectors. I put the new plugs in 300 miles ago.
