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.

HOJU

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

Elton

also may try a new fuel filter

HOJU

Yeah, forgot to mention that one....

Did you check your air filter??

HOJU

first thing

HOJU

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

still nothing-

Elton

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

Elton

Swear at it and kick the tires.

HOJU

Done a LONG TIME AGO.....

Elton

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

HOJU

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....

Elton

so did you get bigger fuel injectors?

HOJU

nope...

Elton

well i think thats part of the problem

HOJU

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
