What is diagnostic code 22 for a 1994 Jeep Cherokee grand limited


That code is for the engine coolant temperature sensor. "...input above maximum acceptable voltage." I would try a new temp. sensor. If that doesn't fix it, you may need to have an engine scanner hooked up, and see what the sensor is sending to the computer, and go from there.
A bad coolant temp. sensor can cause hard starting like your symptoms.

I have a 2002 mazda protege lx giving a P0300 code. scanner also says fuel system OL-fault, what do I need to look at?


Code 300 is for a random miss or loss of power which is tough to diagnose. Since you have replaced ignition parts, it could be an injector or fuel problem. Or a vac leak. Or a cam sensor, but usually a code would be set for the sensor too.

Engine races on startuo


Sounds like a major vac leak, such as the EGR valve.

Problem with idle speed. The idle is controlled by the pcm (engine computer) through the operation of the Idle Air Control valve or motor. But several other sensors are also at work, like the throttle position sensor, the coolant temperature sensor, the MAP sensor or the Mass Air Flow sensor. The computer monitors all engine conditions to optimize performance and driveability-this includes keeping idle speed correct.
Would probably help you if you could see what all those sensors are telling the pcm-so you need a scanner capable of giving live stream data. And don't forget, your '94 is OBD-1, not OBD-II like all cars since 1996 on have. A garage should have such capable scanners, but they are kind of high end, not your typical cheap code scanner.

You could try to figure out the codes they will tell you the problem do a google search for troubleshooting codes for mazda. It could tell you how. You turn the key on in a certain order so many times. a light will flash to tell you whats up with you car. but you have to find the chart from Mazda if they even have this.

This link may give your more info for what I'm trying to explain.
