1999 Ford E150 Sign In

Hello, I have a 1999 Ford E150 that I'm having a problem with. The van started sputtering and losing power while accelerating up hills. The check engine light had been on for something to do with O2 sensors, but I hadn't really noticed any issues and had driven it for over 10k miles before this started happening. While accelerating in the mountains, the check engine light started blinking, so I stopped the vehicle for a while. I continued driving it and have been for a while, and it only started blinking again 1 more time while accelerating up hill. It drives pretty normal on flat ground in city driving and my engine doesn't idle rough or anything. I don't accelerate too quickly on flat ground because I feel more of the sputtering the harder the engine is pushed. I'm in California now, and I'm unable to check the codes by law without having a mechanic do it which would generally require a charge. I'd just like to know some possible problems before I bring it to a mechanic to have it diagnosed. I figure it's best to be somewhat informed. Any help would much appreciated. Also, I'm in Long Beach so if by chance anyone is in the area, please let me know. Thanks a lot

Chris

Engine size? Flashing check engine light means catalyst damaging misfire. Needs to be diagnosed to find out what is causing the misfiring. Misfiring could be ignition, fuel, or mechanically related. Diagnostic testing would figure out the problem.

Much appreciated. It's a 4.2L V6 if that changes anything.

When is the last time it has had a tune up? Missing under load could be from an ignition problem. Spark plugs and wires do wear out over time.

If there are lean codes (o2 codes), that could be from vacuum leaks. Monitoring fuel trims using a scanner that can read datastream information can give you information if there are vacuum leaks or not.

Can't know for sure without more info but that era of Ford engines are notorious for ignition coil issues.
