This started with car almost stalling in Nov, 2007 when I was pulling into parking space. We changed fuel filter. Seemed to run ok until May, 2008. Then code of misfire cylinder 1 started. Next it was misfire on all cylinders, ignition module failure. We have replaced fuel filter again, $10 spark plugs, $60 wire harness from Auto Zone, replaced ignitor from Auto Zone. Oil was changed out with 10W40 last few times, instead of 5W30 per husband thinking higher miles needs this oil. Engine warning light has flashed a few times when I am driving. Engine sputters and will not go over 45 mph at times, then starts running fine. Problem is intermittent until now. Dealership said error code first time they checked was misfire cylinder 1 and I needed to buy their wire harness. Now they said catalytic converter is failing. I am afraid to replace catalytic converter and still have underlying problem that will cause it to fail again. Also we have put several cans of SeaFoam in it and even 2 gallons of racing fuel in to clean out gas.
have the same problem?
