Hi Scotty,

 On a 2009 Dodge Grand Caravan 3.8L.   Check engine light was on for Ignition Coil and a misfire.  Fixed all that.  Now the code is PO204 / Fuel Injector.  At times it runs smooth and times it runs rough.  I could leave the store and it'll be rough and before getting home it would be smooth.

Any ideas on what to do next?

Thanks

well on those, often a failed main computer, the circuit that drives the injectors. Have a pro check that first

Thanks.

I'm unable to have a pro look at it. I just put some Gumout in my gas, and did an oil change which was 6 months past due (sludgy oil). While out test driving it, I made a turn and gradually accelerated, It immediately jerked. Since then, I cleared the codes and today it drove like normal. Could these have caused the PO204 code?
