I have the car listed above that while on the road to Texas stalled out on my wife and basically went into limp mode. Bought and obd2 reader and got codes P0300, P0303, and p0304 stating all misfires. Replaced the spark plugs and still didn’t help. Took to local mechanic shop that was available on Christmas Eve, they checked coils, compression test, they tested for spark and also fuel pressure but the only thing they came up with was the high pressure fuel injectors, spent $500.00 and replaced those but it didn’t fix the problem. They are advising me now to chance the ECM stating that’s really the only thing left to cause these codes. I’m now reaching out trying to get more opinions and advice.
