only reving to 3000rpm? helpp!!!

alex_ · Post by **alex_** » Wed Mar 14, 2007 10:59 am

hi, i finally got my car to accelerate, but it goes as far as 3000rpm then bounces up and down from 2500-3000rpm, it will do this with the throttle all the way down and continue to do this..

.. it's making alot of noise as if theres no air filter on, although it is there and looks all ok

anyone help thank u

if its an auto tranny, then chances are the parking/neutral switch is stuck, the auto has a low (and bouncy) rev limiter when it is in P or N

This may be the cure for that.
Read the last paragraph of this:

i didnt do much, i just had to move the car with clutch control gave it a little bit of revs and away it went,

a few weeks before it broke down i had a slight bump on the right hand side, this could be why, its too wet to check now but i'll have it looked at soon thankss

o2 sensor can cause some trubles sometmes. mine did in the lanos, so much the car actually died, and also would not rev past such a rpm.

Try running with the O2 sensor wire disconected and see if that makes a difference.
A blockage in the cat or exhaust can also cause it to not rev past a certain point.

if you disconnect the o2 sensor the these cars, it may run and rev ok for about a mnute before wishing to shut down.

is there any way i can test the car to see if it can rev up, ie remove the manifold to see if it revs up with the full exhaust incl, cat & o2 sensor not there.. or does that sound stupid

if not i'll try unplugging the o2 sensor as above, though keep the sugestions coming please

thanks

unplugging the O2 would be alot easier. just remember there are 2 of them. if that dont help then take the flex pipe on the exhaust off, then it will be open exhaust, its gonna be LOUD but if it revs normal then you know you have a exhaust restriction.
