Originally the rpms would just drop when i came to a stop. I replaced o2 sensor and cleaned throttle body, it seemed to stop for a week or so. But now it still does it but also when driving if i push the gas it wont go the rpms like stick and the car just is like blah...what could it be ? I have intake and full exhaust. Could there be a exhaust leak or is something loose...any ideas though ect. thanks

 

you gotta wait for the car to downshift?

 

Crank angle sensor?. pull the ecu codes

 

Check For
Clogged Fuel Filter/Fuel System Pressure/Fuel Pump
TPS Sensor
MAF Sensor

When was your last major tune up?

 

I think thats kinda normal in automatics? Mine does the same ****... More after I put on the intake.

 

maybe your intake is sucking in lot of hot air?
