1997 GMC Jimmy - Page 5 - Answered Questions & Fixed issues

Engine check light on? Check all vacuum lines for leakage and check fuel to air sensors.

"Blue Devil Oil stop Leak", Used this in My 97 Jimmy, Also for my Rear main seal..various other leaks.. WORKED! Didn't believe it would..... Stopped all leaks. Every leak is diff. Depends on How bad of course, but well worth the try.Cheaper than pulling those Axles!, If it doesn't I do believe they will refund your $... Good Luck!

You need to post more info on the vehicle. I know that you say it is a JIMMY but that does not work when it is time to find parts. 1500 or 2500? The sensor could be in the MAF device and if that is the case you should have driveability issues and a check engine light. So let us know about these things please.

check for a leak in the gas tank above the 1/2 level it could have a pin hole. it could also be a bad vent valve on the tank or in the EVAP system that needs to be checked out.

There is no replacement for hazard lights, you will have to get them fixed

knock senor

Tried moving the steering wheel firmly in one direction or the other while (gently!) attempting to turn the key? Or look for a little lever that your knuckle sometimes hits when you do turn the key.

push it in when you lock the steering maybe.

Could be the timing / crankshaft sensor bad?

Check that power wire has not been left off the battery or fuseable link blown.

cat converter plugged

Could be. You could take the switch off, leave it in the park position, and see what happens when you shift into drive.

Transmission cooler inside the plastic parts of the radiator may be leaking and causing the oil to mix with the coolant. GM also has a problem with their lower intake gaskets leaking, which would allow the oil and coolant to mix. Last possibility is the head gasket is leaking and mixing the oil into the coolant side but not the other way. Check your transmission fluid for mixing evidence. Another thing to do is pressure test your cooling system (Radiator, hoses ect) to see if there is a leak. Another test to try out is compression.

I would say either the fuse or the switch, maybe a bad wire.

I need better explanation of the noise,there is alot of things that could be making noise in this area of the engine.

Answered that already

If these codes only show after rain then the moisture is affecting the connections in the wires. Pull each connector apart and clean out with wd-40 or other water dispersant and ensure that the connections are water tight. Any dirt ,oil ,grease green gunk on the pins will cause a problem

HERE WE ARE AGAIN STILL SAME ISSUES AFTER CHANGING ALL 5 SOLENOIDS,FLUID,FILTER AND EVEN THE INTERNAL WIRING HARNESS IN 4L60 TRANSMISSION IN A 97 YUKON. STILL GETTING A P0785 CODE. WHEN 1ST STARTED SHIFT PERFECT TILL IT WARMED UP AND I MAKE A COMPLETE STOP. THEN IT WON'T DOWN SHIFT AT ALL AND I HAVE NO OVERDRIVE. HAVE NEVER HAD ANY PROBLEMS WITH TRANS TILL IT STARTED DOING THIS OUT OF THE BLUE. NO SLIPPAGE NO BURNT FLUID EITHER. I'M TOTALLY LOST AND DON'T WHAT ELSE TO DO. CAN ANYONE PLEASE POINT ME IN THE RIGHT DIRECTION? PLEASE EMAIL [email protected]

the fuel is no getting enough mixture when you ask for power.

that is not bad for a 1997 it could be a sign of the battery or your stater getting old but i think your are ok 2,3 second .
