Tech Question
So I bought a 92 F150 with the 4.9 6 cyl. It only has 109,000 on it and was running really good. I did a tune up, new motorcraft plugs, new wires, and put in a new egr valve put didn't put in a new valve position sensor. Well when driving down the road my check engine light is flashing on then ill accelerate and then will flash off. It does not stay on. It starts just fine, idles good, just when your driving it will flash on and off. Any ideas out there?

The best thing you can do to help yourself out is to pull the codes. Even if the light isn't on currently, any codes that were set will be stored.
