Hesitation in Acceleration

[imduke2u]

I just installed Borla Dual Exhaust on my PT. When not in gear and press accelerator engine hesitates as RPM's increase. Any ideas or suggestions would be greatly appreciated.

NEED MORE INPUT! (as Johnny #5 said in Short Circuit)...
Did your PT NOT hesitate a bit before you installed the new exhaust? Most of the people that complained had a hesitation from the very start before any modifications. It's hard to believe that just changing the exhaust has brought about your hesitation, usually it's some sort of modification that's done to the engine that brings about rough/stumbling/hesitation (pick one). The problem has been covered quite extensively in this and other forums and the answers run from fixes on the computer (if your car has a build date before Aug 22, 2000, to disconnecting the negative battery terminal and then running your car the way you want the computer to learn how you drive. Hope that helps a bit. <img src=icon_smile_big.gif border=0 align=middle>

Crewzin,
Thanks for getting back to me. More specifically, when the car is in park or neutral and press on gas pedal when reach 4000 RPM its like the fuel is shut off. IF hit accelerator several times to rev up engine between 3500 - 4000 rpm same result. Its not like I really checked before, I replaced exhaust so I can't compare.. When I was done installing exhaust and I started it up to listen to exhaust is whne I notice. WHen in gear in driving everything seems fine. I was talking to a friend who said car might have programmed into computer neutral rpm limiter. I am going to hop into a stock PT to check out if rpm is limited. If you have any other idesa, or anyone else has any ideas I greatly would appreciate the response.

In another forum, it was noted that if you are not in gear (park or neutral), you have just hit the rev limiter. No worries.

Sci-Fi,


THanks for the "Input".

Exactly; If you increase the rpms too high in nuetral, Chrysler has a "fuel limiter" to keep it from over reving as we are prone to do with the new Duals to sound them off, that we didn't do with the stock system Hah ;o) Ya just can't win anymore, although I hear there is a diff chip, that will by pass that, that isn't recommended for us ;o(

this revlimiting thing ,,,,is it just for the automatics?
or does it do it to the manual transmission too?

problems for me is that when i rev up or when changing gears, the revs seem to stick rather than just drop quickly . is this normal?

With a 5-speed, you can rev to the redline. Mine will go to the 6250 RPM limiter. Sometimes when taking off really fast, gears don't catch like they should, but that's not the same as revving in neutral.

It's normal. The emissions controls holds the revs for a short time before dropping.
