2001 Malibu. Why does the engine bog down when the accelerator is depressed?


I would replace the fuel filter, clean the mass air flow sensor and then scan the computer for codes. You may have a bad throttle position sensor.

Cuts out while driving


which engine option??????????????????????
sensor 2 is not it. sensor 2 is only a CAT test.
Sensor 1 runs fueling at idle and light flat cruise.
the CUTS out, dont tell me anything.
is the engine stalling?
ever tune it up and not buy the most expensive parts in EFI. map, and IAC?

Cuts out>
do you mean it hesitates and then catches up?
does the engine stall and die?
does the wide open throttle work up hills with full power?
cuts out.
if it is only short time hesitations and then wakes up
that is tuneup time, spark plugs, new, spark wires,
read the operators guide, for 60,000 mile tuneups. filters /spark parts.
if it is tuned up, and only hesitatates
try a new TPS.
if it is a deep long lasting full bog.
then the , fuel pressure is low, check that, the guage costs $20
make sure fuel pressure is at spec, first for BOGS.
the EFI system can not run right with low fuel pressure.

all 0xygen sensors are off line, accelerating so its not that
only the front sensors set fuel rates and never accelerating.
the ECU shuts them down then
and uses the map , air temp to calculate fuel rates.
but if fuel pressure is low, it gets all that wrong.
after all , it dont know its low, and can not adjust for that
and most injectors are useless below 28psi.

I have a 1997 lumina with 3.1L. the problem started with loss of power under load and p0300 code. check coils and vacuum leaks both OK.change spark plugs and wires.[same problem] check compression OK.


Since you changed the sensor we will assume it is working. When you disconnect it you put the computer in limp mode which stops it from using sensor values. If code 300 is the only code we will assume the coolant temp sensor and others are ok.
I would check fuel pressure with a gauge next.

On your year the 02 sensors did more for fuel economy. Of course this was a major part. But it did not affect the performance of the car. they would usually run rich and use more fuel. If the wire is from the 02 sensors the check engine light would be on. If you have the early 95 , OBD1, It is getting harder to find shops that can hook it up to a daignostic computer. Later is the OBD2. Most all shops can hook up. The loss in acceleration is probably the fuel filter. At low end you will get plenty of fuel. but at the higher speeds the filter is clogged and. will not let the fuel flow through like it should. You will have pressure , but not flow.. Other things could be the catalitic converter and air filter.

Check engine like is it red or yellow? if it's yellow it could be a misfiring spark plug, or a lazy 02 sensor, that means you drive the truck till it gets in closed loop then the 02 sensor is connected to fuel trim and is not changing fast enough causing the light to come on. Since the 02 sensor is bypassed until engine is warm this could be your issue, it could also be a spark plug wire or even the heater on the 02 sensor, since it's a 89 it has a sensor on each side of the engine and one after the cat, if there is a spark plug problem if the check engine light starts flashing it means a catastrophic misfire that will destroy the cat so it is a fuel or spark problem.

First thing to do is change the fuel filter, spark plug wires, spark plugs, and air filter. If this does not solve the problem then I would have the fuel injection system cleaned out and also change the oxygen sensor

try to have your intake manifold and air filter cleaned. Also, try to replace the fuel filter. these are usually the culprits for the problem that you are experiencing.
