Question about Oldsmobile Bravada

Open Question

1999 OLdsmobile Bravada Service engine light came on and went off. 2 codes po300 and po152. sluggish acceleration. sounds the the vehicle is starting out in third gear or overdrive... very low pitch noise to engine. when you step on the gas pedal as though to pass someone the rpm increases but the speed is gradual. fuel pump was replaced/filter for lack of fuel pressure. another code had been set for the O2 sensor located between the muffler and the cat converter. This is a completely rebuilt engine from Jasper with only about 17K-18K miles. The air cond. also doesn't switch to just outside air with air off...like vacuum switch/line problem??? the flasher noise is also sounding even when the turn signal is not engaged and the sound is stopped by pressing and holding the emergency flasher button down several times

SOURCE: My truck dies out when stepping on the pedal more than a third of the way

Hi.
I read your problem.
I have some ideas about that.
You are right, The pressure should stay olmost the same.
But, I'm , involved in problem with aftermarket fuel pump.
I recomend A/C delco or Carter. fuel pump.

Check the Pressure regulator, that goes in the rail of the injectors. Inside of the intake, Some times is leaking.

Check the EGR valve, The carbon make the valve no close correctly, Take it out and check the pivot, they have to stay close.

Check the ground in all around of the car, speciallity the one on the frame rear , for the fuel pump.

If after all you still have the problem, Disconect the transmission seleniod connector, and put in drive, if the problem go out.
check for short cicuit in the wires and connector a transmission..

Is there more thing, but I hope this help on someting.

If wiggling the wires cured the code, then one of the wires is broken inside the insulation. Pull on each wire one at a time. look for the colored insulation to stretch, this will be the broken wire. For the other car that wont rev up, this is a common when the catalytic concverter is plugged up. This will also cause MAF codes, and in turn, TRAC OFF light.

Try changing out your distributer cap and rotor button. Let me know if that solves your problem.


Thx

2001 Alero was running fine stopped at a light and went to accelerate car started shaking bad, would not accelerate more than 2 mph it seemed. Then Trac Off light came on followed by flasing service engine...


Start the car and have some stand behind the vehicle while it is running in park and rev the engine to see if exhaust gases are coming out, if not sounds like the cat converter is clogged.

Check engine light came on,car starts,but is kind of sluggish


there are over 200 faults that cause the check eng light to come on, so guessing is not an option, you will need to have the computer tested to see what trouble code is stored in memory.

02 Oldsmobile Bravada check engine/reduced egine pwr light on


There are over 2000 different trouble codes that can store with your check engine light. Probably 30-50 of them (or sequences of them) can trigger limp-mode or safe-drive mode on most vehicles. In your case, I would strongly suspect a problem with the electronic throttle control assembly. For safety, vehicles with electronic throttle frequently limit speed and rpm to very low numbers when a fault is detected to prevent runaway accelerations and high speed collisions. Have it checked by a professional. It may be as simple as a sensor on your accelerator pedal, or the throttle assembly itself could be starting to fail. In either case, it shouldnt be played with unless you have the proper diagnostic equipment (a Tech-2 Scantool) and good repair data.

NOTE: Clearing the code with a generic tool or disconnecting the battery MAY allow the car to reset, and if the problem is intermittant, it may become normally drivable till the next time thr problem occurs. HOWEVER...the technician who fixes the car really should have access to the original failure information stored in the freezeframe snapshot the computer took when it set the code. If you reset the light or disconnect the battery, that info will be erased and make make diagnosis and repair much much more difficult.

99 bravada sluggish/hesitating while turning right or left


If youre talking about wheel hop when turning at slow speeds with only the info you have provided I would guess it has smart track AWD and this is normal, How ever if you have push button 4x4 controls your front drive axle could be locked in, in that case have a garage check it out...
