Has anyone ever Had the problems i am having? I have a 94 five speed 2.3 and its wasteing way more gas then it should and its not wanting to pick up speed very good and when ever i go up a hill in 4th or 5th gear it lowers speeds and i have to drop a gear to Get back up to speed wants to shake when it does go up hill in 4th or 5th any Suggestion Nee fuel filter IAC valve Fule pressure reg and T position sensor any help is much appreciated

 

How big of hill and how fast are you trying to go?

What size tires do you have, what gear ratio in the differential ?

A steep hill at 30 MPH in 5th gear isn't going to happen.

 

All of that is fine and ues i have bigger tires on the back but that wouldnt matter woth my 0 to 50 in over 2 minutes seems like its just not getting enough fuel.My pedal i have to put to the floor to do anything clutch is fine seems like it is anyways

 

Welcome to the forum

Any engine will ping/knock under load if it "isn't getting enough fuel", so if you don't hear that then its getting enough fuel...........and it will smoke if its getting too much fuel

Test for clogged exhaust system, i.e. pull out upstream O2 sensor and go for a drive, it WILL BE LOUD, but if power is back then exhaust IS clogged

2.3l Lima has a timing BELT, these can stretch or slip a gear, this causes lower compression so lower power

You can use a vacuum gauge to test "compression" and clogged exhaust, read here: https://www.gregsengine.com/using-a-vacuum-gauge.html

Vacuum gauge is still one of the better tools to use to diagnose gasoline engines
