sense you have a a possible tainted fuel problem
and,if you dont want to remove the fuel tank
the best thing to do here is to run it as close to out of fuel as you can
then,replace the fuel filter and add the fuel treatment....if it is the fuel..this should fix your problem
I had been doing the opposite with trying to dilute the bad gas by keeping it full which it does seem to be running slightly better but not very much. I'm not sure of the relevance but it does run better in 2nd
My father has suggested trying to replace the egr valve, he is an experienced mechanic but hasn't had very much time to play around with it and the weather has been horrible
the 300 code..is this the only code you get?
Yes put it on the scan tool again last night and that is the only code its running now. It says random misfire, in the first few days it said cylinder 4 so he changed the plugs and wires and since then the only code is the random misfire
lets get that fuel out,,,if you run it out or drain the fuel tank first
remove the ignition module
it is located under the ignition coils
most auto parts stores can test these
it is possible that the ignition module is going bad
We had discussed the ignition module yesterday and seemed to find a number of posts from other owners having problems with them after a few years.
it seems you know you got bad fuel
so,,we need to get rid of that first
but yes..it is very possible,that the ignition module is going bad

Any thoughts on the egr valve? Would you suggest trying that or the ignition module first? And I can't be 100% sure that it's bad gas, because it is an older car and could just be due for some replacements but the car was running great until the day I got that gas and when I seen that the entire row of pumps was removed two days later it just seems like the logical conclusion
well..i dont think it is the egr,sense you arent getting a code that really points to it
so,,just get the module tested first
if ,you know it has good fuel,and the module test good...
you may want to remove the egr valve and clean it with carb cleaner
Alright I think we'll head back to testing the ICM before spending 150 on that EGR and I'm glad to hear I can try to remove and clean it before replacing it if we get to that. Thanks and have a good night.
