Oldsmobile - Bravada :: 1997 - Suddenly Bogging Down - Not Shifting Well
Aug 10, 2012
I have a 1997 Olds Bravada with 170K miles. Engine was running fantastic up until three weeks ago. Suddenly engine is "bogging" down and transmission is shifting between gears at certain speeds (like it can't decide---usually around 40mph). Replaced catalytic converter because mechanic said it was plugging. Now engine seems even worse---it feels like it is working really hard, like the brakes are stuck on or like it is pulling a really heavy load. Gas mileage is worse. Trans is still not shifting right...at 40 and 50 mph it can't "decide" what gear to be in and switches back and forth, and at higher speeds it has slight hesitations, like it's "missing" or not getting fuel for a split second. Mechanic said it needs a tune up.
Background: Replaced transmission one year ago with remanufactured trans (could all-wheel drive be stuck "on"?). Replaced catalytic converter. Also just had A/C recharged and began using it about one week before these troubles began. I have stopped using the A/C in case it was related, but the problems have continued.

1997 Olds. Bravada. 4.3L original engine. 217000 miles, maintained well (routine oil changes, fluid checks, etc)
Intermittent stalls. When stalling, voltage found to drop to 0 even though radio, headlights, and dash lights remain functional. Engine will sometimes "automatically" return to running (it doesn't turn over, just runs) and the air bag light flashes, other times it needs to be restarted. No problem restarting, but may or may not stall a few seconds later. No specific action triggers the events. On a potential side note, the rear wiper motor will spontaneously start running occasionally (once per week frequency typical).
Attempted fix: cleaned both battery contacts, removed and cleaned frame ground, removed and cleaned body ground, all done with either sand paper and/or a wire brush

Recently have developed a strong gas smell in my 2002 Olds Bravada. I have checked around getting no where fast I have been told the culprit maybe the fuel pressure regulator but with the engine running and I am under the hood. There is no odor there is no odor outside the vehicle at all only inside...

I've been commuting roughly 100 miles round trip daily for work for the past month or so and other than the need for an oil change (I'm at about 6,000 since the last one, current mileage is 171900), my 98 Bravada has been fine. However, this evening when I was about half-way home, I noticed the car was getting a little resistance on accelerating.
I had wondered if it was the wind and rain I was driving through, but the tachometer was jumping regularly, it was in the lower ranges (between 1-2, maybe a jump to 3). I was still able to maintain speed (up to 60mph, and a struggle to get to 65 - somewhat unusual) - however there was noticeable resistance to acceleration. Once I got home I noticed that the temp gauge was showing less than 150 and the oil was fluctuating between 1/4 and 1/2.

I have a 2000 oldsmobile bravada. When I'm driving i press the gas and it does not accelerate. The engine revs but it does not go. Then it will engage and will drive fine. What the problem is?

I drive a 2000 Oldsmobile Bravada. I just changed the outer tie-rod (passenger side),and there is still a fairly good shake coming from the front end. I have checked everything that comes to mind (true, not too sound a mind). My question is, how would i check the steering gear box?

When driving down the road, usually at speeds greater than 55 mph and usually in hotter weather, the vehicle will just shut off. Temp gauge stays firmly in the normal range, coolant level is fine. The vehicle will eventually restart after 5-20 minutes before repeating it's little 'siesta mode'.(It turns over, just won't start) I've been all over the internet and can find dozens upon dozens of identical problems in 1998-2002 Bravada, BUT NEVER A SOLUTION! There are suggestions from wiring shorts to fuel pump to the temperature sensor to PCM - but nobody has the courtesy to get back online and post if they ever found what the actual problem was. I can only surmise that either people just don't feel like posting the solution, or they are still trying to figure it out (which doesn't bode well for me).

I have a 02 bravada that will not start, or even attempt to turn over. The battery is new, all the interior light are on, headlights work and radio is fine. When turning the key there's nothing though??? What could be causing this???

99 Bravada 4.3L. Key rotates to start but the starter does not turn. I can remove the starter relay and jump it and it starts right up, swapped relay with another one and same thing. Car has an aftermarket remote starter that does NOT cut any wires, only ties into them. The remote starter is seeing the starter voltage from the key, but no signal is making it to the relay under the hood. The relay has 12v+, a ground, the starter post, and the post from the key, nothing happens with a test light with the other end grounded or connected to 12v+.
Second problem happened at the same time, maybe related. The floor shifter will not move when I step on the brake with the key 'on or off'. I removed the boot and move the little white lever and it will shift, but not like it should. All fuses are good both under the hood and inside and it.

We pulled out of the parking garage going up the hill it acting like i was in neutral all of a sudden. it was running fine but i was coasting backwards. After checking the tranny fluid it was mostly gone so as my wife and kid sat in the still running car I went for fluid. I put in in and then drove up that hill went around the corner and it did it again. Then i got towed home. When its cold it works when I drive a little this happens. Its on all gears and no matter how much gas I give it there is no attempt at shifting and no weird noises.

My C.E.L. (check engine light) flashes whenever the rpms are over 2000. I had it plugged in and the code was for "random cylinder misfire" all this was after I changed plugs, wires, rotor and dist.cap. What is going on? Its a 2000 olds bravada.

Whenever I completely engage the clutch after shifting into 5th, there car bogs for a second if I give immediate throttle after shifting. It doesn't happen if I wait a second or when driving in fifth gear.

I have a 97 Bravada. Recently the check engine light came on and then went off. I didn't think anything of it at the time till the other day I drove it to work and back fine without any issues, then the next morning I tried starting it and nothing happened. No cranking, no interior lights, no sounds.
I tried jumping it thinking the battery was dead but that didn't work. Now my key is stuck in the ignition in the accessory position. It will not turn all the way back to release the key.

I recently bought a 1997 Ford Taurus. It ran fine when I got it but the third time I drove it, it started acting up. I was driving down the highway and I noticed it was missing a little bit. Then about 10 minutes later it started not being able to keep up speed. It just seemed to kinda bog down or something when I gave it more gas. The longer I drove the slower it would go until it eventually stopped. I took it to a mechanic and he said it was a cam sensor and cam synchronizer or something like that. When that didn't fix it he said it was the fuel pump and filter, which didn't work either. Took it to another and he said to try changing spark plugs and then coil pack after that didn't work. It runs fine when I first start the car but the more I push the accelerator the faster it starts bogging down.

I have a 98 with the 4.2.The troubles started with popping a little through the exhaust ,bogging down and bucking,rough idle and had the two codes together that deal with having bad intake gaskets don't remember the codes offhand.
I also noticed every plug in the truck was wet and black however it didn't appear oil wet.I have changed the fuel filter,spark plugs,lower intake gaskets,plenum gasket ,injector o rings,checked injector ohms all were 16.5,new EGR gaskets,all bolts are torqued to specs
Now I have a no run condition, it will crank but not run. I heard a pop in the engine one time. I cranked till the battery went dead.I also noticed as I was calling it a day last night the radiator reservoir was empty. I don't know if somehow I got a hydro lock even though I put new intake gaskets in it or i have some other issue like timing or something. I don't know where to look next....

I have a 1997 88 with 79k. When the engine is warm and my foot is off the gas, the car occasionally dies. I can restart it each time this occurs.

Three weeks ago my 1997 Oldsmobile eighty-eight (75K miles) shut off while I was driving. I was able to pull over and restart it immediately. This morning it happened again, same exact way. It shut off without warning, nothing seemed out of the ordinary, except for the shutting off! For the past few months my check engine light has gone on and subsequently turned off two-three days later. Most of the time when it turns on, I have been driving on the interstate for an extended period of time:at 70 or 75 mph.
I had it looked at once and they said the light was triggered by the transmission- they serviced it but I didn't notice much difference. Occasionally, I feel the car stutter while slowing down, almost like it might stall-but it never actually has. Finally, ever since I got the car-two years ago from my grandparents, there is a pull occasionally when I am going about 40-45mph and speeding up-almost like it is having trouble shifting. I don't know if all these issues are related...not sure who to trust to take it to. What could be going on?
