I Have A 97 3.8 Car Has Been Sitting For A While
I Change The Plugs, Wires Runs A Little Better ,
But Still Running Chitty
I Check The Fuel Presure, About 42, And When I Rev It Up Goes To 50
Any Thoughts ?
Thanks

 

Since it's been sitting (how long?) I'd run some new gas through it, some ignition cycles and see if you get any codes.

 

Seafoam may help a little.

 

I would change the fuel filter and put in a fresh tank of gas.

 

I WILL TRY THAT TODAY,

 

Ok,
Drained The Old Gas Out,
New Gas, Gas Filter, New Coils All Three
Runs A Little Better
But Very Little Power ?????????

 

So there are no codes present, or an SES light? Is the car misfiring at all? Sometimes when cars sit for awhile, it makes for a nice home for varmints. Are you sure nothing has nested in your intake or chewed up any wiring?

 

There Is A Misfire Code
Took The Complete Air Cleaner Off, And Checked
Sprayed The Maf And Tb Out With Gumout?????

 

Is it a misfire specific to one cylinder, or is it just a general misfire code? Maybe the injectors are gummed up a little bit from the gas sitting too long. You might want to have the injectors flushed or have the car scanned further to find out exactly what the misfire code entails.

 

car is running 80% better
now the code is 0306
rechecked the plug, wire, and has a new coil pack ???????
on number 6 clyl
withen 15 seconds of turning of the check engine light,
it is back on, car is running pretty smooth,
thanks

 

Good luck bud i had a missfire on #3 in my 96 3.8 turned out to be an intake gasket (after spending oodles on the ign system thinking that was the prob)
