Australian Car Repair Issues? Ask an Auto Mechanic for Answers ASAP
Hi Im David, thanks for visiting the site. the power steering pressure switch has nothing to do with this problem. its going to be the transmission that is the issue here. seen it many times as people make the mistake of replacing the engine for the exact same problem before having it properly diagnosed.
the only other possible engine component that could cause this issue is the mass airflow sensor. un plug it and see how it revs.
ive seen this happen also. was the same mass airflow sensor used ?
yes, thats it.
leave it unplugged and start the motor
see if the rev point changes
ok, thats unusual. did you happen to replace the pcm from the other vehicle also?
check engine light on?
better yet, do a back pressure test to make sure the catalytic converter isnt clogged
Im out of ides my friend. maybe have the computer reprogrammed. ill opt out and see if another tech has an idea
do you still need help???
Hi. I would like to add, just because the cats are the ones from the replacement engine, it does not mean the exhaust is not plugged further down the line.
