I am tryin to fix my car; I originally had the gear 1 incorrect ratio code I managed to fix that. I changed my transmission filter, I changed my fuel pump, changed my throttle position sensor, mass air flow sensor, ignition rotor. I am tryin to get my car back on the road. After I changed the throttle position sensor, changing my transmission filter and adding more transmission fluid; it started not going past 3000 rpms. That is when I changed my fuel pump assembly (just did that today) and it still won’t rev past 3000 rpms. I need help if someone can help me that’ll be much appreciated thank you!

It's in limp mode. You need to go get a scanner and check for stored codes, otherwise you (and we) are just guessing.

Welcome aboard!

I paid a mechanic to look at it with his scanner and he was only able to guess too. I’m gonna take it a shop hopefully Tuesday for them to hook it up to they’re computer and see what’s going on. And go from there

Why not just buy a scanner? They're not expensive.

I did, prior to doin everything I done to my car I got the mass air flow sensor and gear 1 incorrect ratio. After I put the transmission filter and put more transmission fluid the car and a new mass airflow sensor everything was working fine then all of sudden it started doing it again and the gear 1 incorrect ratio hasn’t shown back up again. I also had a mechanic come out to diagnose my vehicle and that didn’t help either cause he couldn’t pin point the issue the only thing he said was to try changing my fuel pump assembly and see if it helps and it didn’t. So my last step was to just go to a shop and have them hook it up to a computer or try changing my CAS

I was also thinking too awhile back I got a code P0731; I added more transmission fluid to my car clear the code and it hasn’t shown back up. Do you think it is possible I need to replace my shift solenoid? If so do you think that’ll fix the issue?
