Problem with my Olds Alero
v-6
codes = no
work done prior = none
work done to repair = fuel filter and spark plugs
tech = jk
question = the car chugs when you go 35 or higher like it not getting
gas or something . It has got worse since i changed spark plugs what
can be doing this
JK:
There are many things that can cause this condition. Engine related, or transmission related.
If engine related, could be corroded ignition coil towers under the spark plug wire boots, low fuel
pressure caused by a plugged fuel filter or weak fuel pump, plugged catalytic converter, faulty
MAF(mass airflow sensor). But these things will usually cause a check engine light and codes to be
stored.
Could also be transmission related. Would suggest having a mechanic drive it to determine where
to start diag. Have had trans. problems that feel like an engine Driveability problem, and an
experienced mechanic may be need to determine this.

Oldsmobile Alero 2001
Warning lights = low tire air and service engine soon. All codes were recemtly reset. The codes were
reset so to reduce the idling of the car. Because that was supposedly the issue.
Question = I recently (in the past month) went to the shop to get the codes reset on my car to cure
the idling it was doing and I also had my ac fixed also. As of 2 days ago, My car has started idling up
and afte it does that the know goes back down and the car starts to jump lightly and then it will cut off
completely. Could this be a battery issue or something more?

Answer: I would have the throttle position sensor checked out,
I bet that is your problem. When they go bad, they will cause
erratic idling, surging, and/or stalling. There is a spring inside
the sensor that breaks and then there is no tension on sensor
to keep it correctly timed with the throttle blade. When there is
a mismatch, even over a bump this can happen, the idle can
rise dramatically, or get so low the car will die out.
