Hey Everybody,
I've been reading these forums for quite a while and learned a lot about my vehicle. Had a bad experience with a mechanic in Maryland and after I got to Florida decided to take a more hands on approach with any simple mechanical repairs.
With that being said, 2 weeks ago my vehicle had a P303 code - cylinder 3 misfire. The car had a lot of problems when it was idling the RPMs were too high (2k+).
So I purchased and installed 4 Bosch Platinum Spark Plugs, and also replaced both coil packs. I also ran Techron fuel injector cleaner.
After that the problem went away for a couple of days until it started having problems with acceleration sticking every time the gas pedal was pushed after coming to a complete stop. From the outside it must look like my vehicle has a standard transmission and i have no clue how to drive stick!
Anyway the check engine light came back on and was flashing more often than before so I checked the code and now it does not idle at a high RPM but its a Random Misfire (P300).
I am also only averaging a HORRIBLE 17mpg now!
Here is where I am looking for help... I need to know what else it could be and suggestions on how to fix this problem myself, as there are no other codes...
I believe it could be any of the following:
Bad spark plug wires
Bad fuel injectors
Bad EGR Valve
Obviously I don't want to have to replace all of the above but I do drive all over for work so need this to be fixed ASAP.
Thanks in advance!
