95 ranger 2.3l Truck will spark knock badly when going up hills or at 45mph or better when acceleration is needed. You said to change the knock sensor. This truck doesn't have a knock sensor. Can a worn timing belt cause the problem. Please give the possible reasons. Thank you.

I am assuming you have the 2.3 liter 4cylinder engine.. This is common in all rangers straight out of the factory with that motor. Your asking alot out of a 4 cylinder truck that also get good gas mileage. they just do not have the capacity to gain speed up a hill. There are a few solutions for you that you could try. If it is a 5 speed manual transmission try to speed up before the hill and when you start losing speed go to 4th gear. this is also good for using as a passing gear as im sure you have noticed you lack power when trying to rapidly accelerate at highway speed to pass. an aftermarket cold air intake combined with a less restrictive exuast will give you anywhere from 5-20 hp gain AND give you more MPG's
Or you can buy a light truck with a v6 or v8 in it. rangers can be equipped with v6 as can chevy s10's. dodge dakotas have the availability of small block v8. this is of course will cost you alot in gas (based on experience) I am a 10 yr mechanic and have owned 2- 4 cylinder rangers a 93 and a 94 my dakota which i still own is a 01
The knock sensor code does not always mean the sensor is faulty. The sensor picks up noise and vibration in the engine such as a spark knock would generate, and the computer slows down the spark timing to fix it. If the noise or vibration continues, the code is set. Could be a noisy valve, or a problem with the crankshaft or other component.
I am assuming your transmission is a 5speed manual. What is the tachometer reading when you experience this jerking in 5th gear? It sounds like the engine is being lugged. If you are trying to pull a hill or accelerate in 5th gear at less than 40 or 45mph, you need to downshift to a lower gear.
On passenger side, inside of cab there is a fuel inertia switch mounted
on the firewall by where feet go. There is a button underneath, push it.
This will reset switch. Truck should get fuel now and start. These
switches get weak and if passenger kicks it truck will shut down. Will
still turn over but not start.
whether llight is out or not you should be able to pull codes the plugs are a bear to replace and are there to assist in emissions check the ever faulty ford egr valve for your ping problem hope i helped alanwrench
you need to do a top end engine clraan buy from the GM dealer the top engine cleaner clean the engine and also put mid grade gasoline in and put in lucas gas treatment and see if it helps. Clean air cleaner and replace PCV.
