Need help ASAP

Hey guys
my truck started freakin out this afternoon. I was driving off from a stop sign and got on her a bit, not floorboarded about 3/4. Then cruized up to about 45, then maintained, but a few minutes later, it dropped in rpms to 500 then surged to 1000 and went back and forth for a few seconds before shutting off. i pulled over turned the key off. turned it back on and started just fine. drove it to the autoparts store to see if it threw any codes. it didnt, but it drives fine as long as i dont accelerate hard. Any ideas

Yeah, thats my first thoughts, CPS, you may have to pay full price, or take it to ford and pay the $100. It will be cheaper that way. Then once you get it fixed, Get you a spare. I know they sell them on ebay for pretty cheap.

would that have thrown some kind of code though. Cause the service engine soon light flashed the whole time it was freakin out, but then just went off and didnt come back on.

If the check engine light came on it should have stored a code. But like they said it is most likely the cps. I dont know what kind of code reader was used but from my expierience the cheap ones that are sold at autoparts stores arne't very good. I bought a mac mentor and i've pulled codes out of vehicles that a cheap wouldn't pull

Make sure

your spare is a Ford one to replace the autozone one when it goes out.

i would buy only OEM cps sensors!!! I just had to send two aftermarket ones back to carquest the would start to die out at about 2000 rpms but would work fine at lower rpms...put an OEM one in and had no more problems!!!
