hello,

i have a 94 pickup with the 22r. i purchased it from my dad who bought it new. anyway it just rolled 200k is there any special service i should do other than the normal oil & lube ect. also i do have a engine light that comes and goes all the time, and it runs kind of rough @ low rpm. so far i have had the timing belt replaced @ 150k and inj cleaned. other than that it is stock.

thanks
Tony

 

Let me be the first to welcome you to YotaTech.

Well, if your dad bought the rig new, then you know its history which is very helpful. I'd go after the check engine light for sure.

Other than that, I'd just go through everything, checking against your dads maintainence records. Check all your fluids (including tranny and diffs), belts, air filter, plugs, wires, cap, rotor, brakes, wheel bearings, drive line, bushings, shocks, fuel filter, etc. Give everything the once over and make a list. Tackle things in a logical order, starting with any safety concerns. Start your own maintainence log indicating the date and mileage of all services done. Buy a service manual if you don't already have one. And don't worry about any modifications until you master the basics.

Good luck and welcome aboard!

 

i have done most of what you said, the only thing that has got me stumped is the engine light, it seams to come on when it is colder out. is there a sensor that needs replaced or egr valve? i had the fuel inj cleaned about a year ago, i change the plugs every year and wires about 2.5 years ago. i bought the truck with 150k on it, and i have been trying to figure out the engine light for over a year.

 

Check what the code is by jumping the TE1 and E1 terminals on the diag port. Turn the key all the way, but not the ignition...and count the Check engine light blinks. The computer should have the code in it's memory unless it lost it somehow. If the light just blinks constantly, there's no code.


That'll give you an idea where to look. But if it goes on and off, probably just a dang wire or something, no big deal.

 

Welcome!

At 100k, 200k etc, I go through and replace ALL the fluids, belts, hoses, cap/rotor, plugs, wires, etc - kinda like a clean start.

If you have a check engine light, you must have a 22RE, not a 22R. (22R is carbureted - no computer to activate a light!)

 

The check engine light on older rigs is related to what the O2 sensor reads and thats it. It sounds like when its cold your not getting a good combustion in one or more cylinders causing the O2 sensor to detect a problem. You also could have a bad O2 sensor. Check your owners manual, many of them say the dealer pays for cost of replacment.

I agree with TC, change it all. I also like to run a high quality fuel injector cleaner jsut prior to the fuel filter change, just incase it pulls some crap from the tank too.
