I just bought a 91 N/A Auto tha thas a hesitation/vibration under acceleration between 3500-4500 rpm. if you 'drive it like you stole it' it will shift fine and you barely notice it, but if you try to drive like a good boy, it doesn't like to shift in this range either. Any ideas?

Thanks!

 

you shouldnt have bought a car with a problem is my first idea.

 

and dont take that as me being an ***....you just shouldnt have im not tryin to be mean....also...welcome to zdriver.

 

Welcome, Hollywood! Have you checked the ECU codes? That would be the place to start in trying to find the problem, since there's so many things that can cause hesitation.

 

maybe your transmission. i dont know much about the autos, but this might help if it is the tranny problemHKS ALC

 

yeah me niether on the auto otherwise i woulda threy somehting out there....

 

First run ecu codes. Is the speedo working correctly? That, the coolant temp sensor and the TPS all provide inputs to the A/T ecu regarding shift points.

Then run the A/T diagnostics ---->>>>> HERE

 

Bad linkie, Canyon.

EDIT: NM, I fixed it for ya. It works now.

 

LOL .... thanks, I was fixing it at the same time.

 

Thanks... hopefully i can get some time to look at it this weekend. Also, thanks for the welcome everyone, and snwbrderphat540, I bought the thing for a song, so I was willing to take a chance or two with a few things being wrong.

 

Welcome, hollywood. If you need a tranny, i got an extra.

 

what does that mean you bought it for a song?

 

like a birdie sings----cheeeeeep cheeeeeep-- easier to fix that way-----?!
