I'm sure when you replaced the tps you "set it properly" using a volt meter so that you have the correct voltage at idle and WOT.

Have you tested/inspected the coil and ICM?

Also just so I'm clear, you are have no codes now.....correct? Do you remember the ones that were there?

 

In may these codes were reported: P0401-egr insufficient flow. In the order notes were p0420 catalyst efficiency issue, p0441- evap system incorrect purge.

They claimed to have cleaned the egr passageway and they cleaned the fuel injectors, and replaced fuel filter.

 

Would it possibly be the ecu or throttle body that i need to look into?

 

Verify the ports were cleaned.......Verify the other things - what are the voltage readings from the tps at idle and wot?

Last...put your car info in your signature line so we don't have to re-read everything to remember/know what year/trim level/engine we are dealing with....Thanks

check those volt reads in the am and get back to you as soon as possible. I do know that im looking for it to read out .5v closed and 4.5 open

 

The ECT sensor could possibly be the source of your idle problem.

 

WILL A CODE APPEAR FOR ECT?

STARTED CAR UP AND IT STARTS JUST FINE WHETHER HOT OR COLD, BUT IF ANY ACCELERATION THAT RPM OSCILLATES AND CAR STARTS TO RUMBLE.
ect checked out ok
ALL SENSORS CHECK OK
