It runs but the idle bounces between 1&2K the check engine light flashs off and on and it back fires. I dont get it ! HELP!
find out what code its throwing first.
how do I do that? No scanner 
You don’t need a scanner. Search. How to read a cel has been discussed countless times now. There’s even a teg tip on it.
:werd:
i thought he knew that already on how to figure that part out… the resources are available, and for free, so use them.
So how would you figure this out if the cel doesnt come on?
exactly
The CEL does not cover every problem that arises. :roll:
Parts can fail that don’t even trigger a CEL. Think.
the cel is triggered when something in the motor runs improperly to where it affects emissions. when it does that then yes u will get a check engine light.
but mi_da_dc_eg u stated in the top that the check engine light does flash. had u read the teg tips or searched, u should know to find out what codes are being thrown from pulling the carpet back on the passenger floor under the dash. if u look at the ecu cover… there is a lil window there and a red led should flash once u start ur car or even just put it in the on position. the teg tips explains the instructions.
u should start with that and figure out what cel is being thrown. then u can worry about the other stuff if there are any other issues after that has been resolved.
But he already knows that the cel light is on so it would help him to first find out what is causing the cel light to come on
… ty for just restating what has been stated.

Check your distributer, take off your cap make sure your getting the voltage at your igniter module if that’s gone it will cause your car to backfire or even not start and it puts the tach out of wack because the run to the same output
