Get a new mechanic

Any check engine lights? Any sounds? Are you getting spark at all the plugs? Does it feel like its missing at all? Fuel pressure? Did any water get pulled into the air intake?

And learn to write sentences. I can't tell what the heck the problem is. Mainly because the post is unreadable.

Well I'm new to the forum but i was really hoping someone could help me out. I recently bought a 2001 f150 single cab short bed 4x4. I got a really good deal on it cause the check engine light was on and it has 180k miles....

Anyway the light was due to oxygen sensors so i bought it. After a couple days i was playing with it offroad, i happened to break something. Now every time i accelerate from a stop the truck has no power, i can floor it and it will barely budge it takes almost 30 seconds to get up to 40mph. I took it to the mechanic i always take my mustang to, and he says he cant figure it out. Now its been in there for almost 3 weeks and hes not even touching it anymore whenever i ask he says hes too busy or still cant figure it out. Can anyone tell me if theyve ever had a problem with acceleration like that it drives fine when up to speed but just not accelerating? Also its a 4.2 v6 with an automatic tranny if that helps. sorry for the long post guys but i dont know what to do now

 

Ahhhhhhhhh.......Now I understand.

What was the exact code it was throwing for the oxygen sensor??
Did you ever replace the sensor??
Is it throwing any more codes now??

Engine missing?? Or just a general lack of power??

Did you happen to swamp it in a deep water hole when you were "playing" off road. I take "playing" to mean you were simply out thrashing the p!$$ out of it.

 

Well i wouldn't say i beat the hell out of it off road just a little puddle of mud didn't even cover half the tires. Anyway the codes were oxygen sensor 1 and oxygen sensor 2 i was told it wasn't a problem and i don't need to replace them, however after i "played" with it and took it to the mechanic he said he pulled up 30 codes 5 of them being transmission codes.

 

Well I would start by looking at those 30 codes, thats one of the best indications of what could be wrong.

 

This sounds like the EGR valve is stuck or the pipe from the manifold to the EGR is clogged up. Clean the EGR valve and run a wire through the pipe to make sure it if free of obstructions. I strongly recommend that you never leave a vehicle with a mechanic that is not fixing your vehicle. If he does not know what the problem is, take your truck back. If he gives you a hard time about it, call he police. If he tries to hold you up and demand an unreasonable amount of money, call the police, pay him, take your truck back, get the police report,and sue the guy.
