SOURCE: 2000 GMC Jimmy Transmission Whine

I recently took my vehicle to a transmission shop and they had to rebuilt the transmission right through. I was recently told that the transmission is a common problem in these vehicles. Sad that GM can not fix or recall the transmisison since there is a problem.

These models had a problem with the electronic control modules, and this is what controls the idle speed. Sometimes they just need to be cleaned, but sometimes they are defective. Volvo has extended the warranty on some of them to 10 years or 200,000 miles if it is found to be defective.

SOURCE: 2001 gmc jimmy not starting

Did they do a fuel pressure pressure test to determine that its fuel pump? And if so what was the p.s.i.?It should be around 55 to 60 p.s.i. a few pounds under 55 p.s.i. Pump needs replaced, Your shop should have chk. this when it was there the first time. Did they by chance chg. the fuel filter, that can hinder it from starting too.

Why does my 1998 gmc jimmy rpm drop so low when its warm causing a miss in the engine


The truck ECM computer controls the idle speed based on a number of engine parameters. Idle drops to a minimum preset level when engine coolant reaches normal operating range and the engine goes into closed loop control. This idle is typically set at around 575 rpm, and cannot be changed without reprogramming the ECM. The miss is not caused by the idle speed - unless the engine is tuned properly and has not lost compression, this idle speed can result in a rough running engine at idle (typical with older 4.3L Vortec engines). Best bet is to get a complete tuneup which will include checking the O2 sensors, catalytic converter and cleaning the IAC valve and throttle body.

1989 Jimmy S15, 3/4 350. I want to change the timing? I have added an HHO generator and need to forward the timing to get fuel saving benefits.


Loosen the bolt at the base of the distributer on the passenger's side. If you don't have a timing light, mark the dist and intake manifold so you can put it back exactly where it was in the event of a problem. Turn the dist counter-clockwise just a tiny bit and the idle should raise a little.

2001 gmc jimmy 4.3l.idles low and will stall when put into gear unless engine is reved up a little.


Clean the Idle air control valve (IAC), it's located by the throttle body so the best thing to do is give the throttle body a good cleaning with throttle body cleaner. Do not use carb cleaner, it's to corrosive for the gaskets used on the throttle body's. Just follow the instruction on the spray can and after your done putting everything back together. Turn the ignition key's to the run position for 10 seconds and then off for 10 seconds to reset the IAC. Start the engine and let idle for 1 min and go for a test drive. If that does not work, turn the ignition to the run position and pull the ecm(BATT) fuse out for 30 seconds and then place it back in start te engine. The engine may stall but let it, don't touch anything. Just start it again and let idle for 1 min then go for a test drive. The ECM is just relearning the sensors like the first time the jimmy was driven off the assembly line. Good luck and hope this helps. Keep me posted be glad to get your jimmy running 100%.
