acceleration problem today?

Post by 95autoturbo »

car starts fine, idles good, but when in drive after second gear (auto) the car will not get up and go? when I try to force it it seems to be confused on whether it wants to go or slow down, at the same time the engine does not rev past normal when I apply gas.......

1. Do you think it is a clogged fuel filter?

or

2. A faulty pnp switch?
yes......It is an 850!

Sounds like fuel delivery problem to me.
Help keep MVS on the web -> click sponsors' links here on MVS when you buy from them.

Also -> Amazon link
. Click that when you go to buy something on Amazon and MVS gets a cut!

new fuel filter today, 32bucks at autozone
drove to work and she had no shame getting up to speed ,although I only took it to work and back.

Its amazing - I have never seen so little fuel leak out from a fuel filter change, and I got worried at first cause the fuel lines were so thick, I usually vice grip the lines to keep the fuel from flowing out, but not on a 850.

Taking my time it took me 15min to jack it up and get my tools to the time I had everything put away, the 17mm open end wrench pulls off the lines perfectly!
yes......It is an 850!
