hi im new here and ineed of some help.

A few months ago my Ac belt came of , I drive without because people told me it was fine.3 days later my car felt like my clutch was slipping. I put on new wheels , changed the belt , I was messing with the air filter and fuel filter and my car got better. Only now it was very slow hard to accelrate and grinding noise came from the back.I change my bearings and nothing happened I changed my differential and it took the noise away and my car is running okay now.But after all that it still feels like it lost power , I cant accelerate as fast as i want to and seems to have a hard time doin so. PLease help , should I take it the the shop?

thank you for your time

 

Anyone ?

 

Welcome to ZDriver!

Your post isn't too clear, and that's probably why no one has responded to you.

I read your post several times... so you just started replacing stuff until the sound changed? Have you pulled the ecu codes? Did you verify that the new diff has the same gear ratio as the stock one?

 

Is the car misfiring at all?
did you do a compression test?
A car needs three things to run
spark, fuel, compression
if your engine has an issue with any one of these you will experience power issues if worse a no start

 

Haha sorry bout that , I havent pulled the ecu codes yet ill do it 2m and how do i check gear ratios?

sorry bout this im new to cars aswell.

No misfires n havent done a comp test.

the thing is the car has power but its not pulling

 

The twin turbo had an r230 rear diff the n.a. had an r200. If you put a TT diff into your non turbo it'll feel slower.

 

The diff I put in was from a non turbo 90' to my 94 non turbo


How much difference would a bad air filter and fuel filter be?

 

It can be pretty bad
the stock airbox has a lot of restriction already plus a dirty clogged air filter will really limit the amount of air entering the intake and oxygen is everything.

Soo a dirty air and fuel filter will make a difference but not a major difference
it will drive smoother and cleaner to have those replace

 

Thanks !

I finally found the problem my rear right wheel moves forward back n forth about 1" when jacked up. I think it's an Axle

 

Ball joint is my guess, doubt it would make the car feel slow.
