Question about 2005 Buick Rendezvous CX

1 Answer

My 2005 Buick Rendezvous will not go over 4000rpm when idle. When on the highway, it loses power when I try to quickly accelerate.

I just replaced the mass airflow sensor, the fuel filter, did diagnostics on the fuel pump (no issues), replaced the air filter and serpentine belt. I also replaced the spark plugs and plug wires, and did a transmission fluid flush. This problem started before all of these repairs, and still continues after them. Any advice is greatly appreciated!

SOURCE: my 2002 buick rendezvous will not go above 4000 rpm's. The engine loses power and feels like it is misfiring.

I would check into replacing a fuel pressure regulator its easy to install and it usually under 10 bucks.

Service engine soon p0135 & p0301 codes


Well the codes are not related.
Code 135 is for a problem with the heater circuit in the front O2 sensor, and code 301 is a lose of power on cylinder one.
Code 135 could be the sensor or the power source for the heater, and code 301 could be fuel or spark related.

I have a 2005 buick rendezvous and sometimes when i put it into park it will idle at 3000 rpms without pressing the accelerator.


First have a diagnostics test done. It sounds like the throttle position sensor is out, or the EGR valve. The EGR valve will most likely be the cheapest part for replacement, and the most likely issue; however this is why I suggest a diagnostics test. If you cannot afford a technician (recommended) then I suggest having a local parts dealer (call around first) do this for you (usually a free service) to identify which part(s) (codes will be listed) need replaced.
Please let me know if you need further assistance.
