I have a 1997 accord 4 cylinder LX and I've been having one problem after another so recently i had oil in spak plug 3 and 2 so i had the seals and everything replaced so then it started to idle rough and then it started to just randomly die on my when i was driving so i took it to a mechanic to do test on it and he said that it was ignition switch and it was misfiring. So he said the ignition switch was a recall so i took it to a honda dealer the replaced the part free of charge and it still idles rough but doesn't die on me but now im getting really bad gas like about 100 miles to half a tank.
Could it be my spak plugs? I just replaced the wires so i know those are good.
And could when i had oil in the spark plugs cause the spark plugs to be damaged and need replacing.
HELP PLEASE im going broke with this car!!!!!

 

Could it possibly be a vacuum leak? or maybe a bad ERG Valve
