I'm starting to notice a hesitation when I get to 2500rpm or so.... It acts like it's getting staved for fuel but then it also acts like it's choking. After 3500rpm it seems fine. I've thought about the MAF, plugs, fuel pump, hopefully not the tranny.


Any tips or suggestions would be great.

 

i would do a tune up and clean the maf then go from there

 

Is your's a 5-speed? Mine has been doing the same thing, but usually only when it has been sitting for a while, like overnight. I can't figure out what it is so if you find out let me know.

 

Jonathan, It's an auto.

Elton, That's kind of what I had in mind. I even had a suggestion to do a fuel system flush

 

also may try a new fuel filter

 

Yeah, forgot to mention that one....

 

Did you check your air filter??

 

first thing

 

Ok, I've cleaned the MAF, and air filter, and have replaced the fuel filter....

still nothing-

 

did you change the sparkplug wires and plugs yet ????.........i just did a tuneup on my 4runner 129k on stock plugs and wires it ran fine before but it runs way better now

 

o you have a supercharger did you do the fuel mods

 

Swear at it and kick the tires.

 

Done a LONG TIME AGO.....

 

have you done the supra maf swap yet ?

 

if you have a s/c w/ no fuel mods that would be my first geuss that you're starved for fuel. or plugs

 

I've had the charger for almost 2 years with no issues. I've thought about the supra maf swap, but it's been suggested that you need fuel mods in order to do it.

I took it to auto zone and no codes came up. The guy there has a 4runner and thought it could be the TPS....

 

so did you get bigger fuel injectors?

 

nope...

 

well i think thats part of the problem

 

I think that if it was a problem it would have happened soon after the charger went on, not almost 2 years later.... they might need a good cleaning, but I don't think they are the issue at hand
