hesitation upon acceleration??

Today my 2007 Taco (14K miles) started hesitating upon acceleration, especially around 2000 RPM. Then I give it some gas, it goes, then slows, then goes then slows. I wasnt sure I was gonna make it over a hill!! Just cruising along seems ok, but when I hit the acceleration it heaves!! THe check engine light just came on as well.

THis is my first problem with it....any suggestions??

definitely under warranty....take it back to the dealer. check your gas cap first, it may have triggered the cel. it may end up being a faulty sensor from the factory, or maybe even a vacuum line that came unplugged.

 

thanks! I checked the gas cap first thing...no problem. I am headed to the dealer right now...will let you know what they say. many thanks for taking the time to help

 

its what im here for!! well, that and beer!!!

 

Get this!! The toyota mechanic took it for the test drive and it broke down on him on the freeway....had to tow it back. Certainly under warrantee, but also certainly not good!! Yikes!!!!

 

That sounds like MAF failure. Let us know.

 

yes,definitely let us know what it turns out to be!!!

 

ok....the dealer says it is the fuel pump....new one to be installed. Hopefully this will fix the problem!!!

 

Glad it worked. Scary that it's on a new truck, though. Things happen.

 

very true......but better now, then when its outta warranty!!

 

That sucks.

 

AND I was glad it broke down on the mechanic and not me!!! Hopefully all will be fixed and I will once again love my truck!!
cheers!

Tell you what, I am a lucky S.O.B ( OK just an S.O.B. ) but I have had nothing but complete JOY from my truck. I broke the tailgate latching mechanism, by slamming the gate closed with the area between the gate and the bed full of gravel ( bad, very bad ), cracked the tail light lens ( loading firewood ) I have scatched the living hell out of it ( too many things to mention ) but all these things were generated by said owner. I'll be out of warranty by spring so I better slow down. Good luck with your fuel pump and your truck. Drive on.

 

I have a 06 v6 Taco. when I bought it used 123,000 it has a hesitation when I get on the gas to pass someone. it runs good other than that . what could this be ?

 

bump for answer, did you get this solved?

 

Yes...can't remember the problem as it was a while ago ( might have been clogged fuel line). Just sold that truck and got a 2013 TRD sport...love it!

 

I was thinken it was normal since its a electric gas peddle.

 

I think your fuel pump problem was also self inflicted. 2007 with 14K miles, get out and use it. The fuel pump atrophied from lack of pumping action.

 

Well than that's better!
