Poor Acceleration on 1999 Corolla VE

[plowther]

Hello,
My question is if anyone has seen a problem with Acceleration of their Corolla? (I have close to 190,000 miles on it)

I have done the following:

1. Replaced the plugs and wires

2. Replaced O2 sensors

3. Put in Techron fuel system cleaner

The car sometimes needs to have gas peddle to the floor to respond.

Any Ideas?

is it an automatic or manuel for starts

[plowther]

It is an automatic.

dirty mass airflow sensor? 190k miles, have you changed the upstream oxygen sensor?

[all2baka]

1. 3 or 4 speed?

2. Have you cleaned the air filter?

3. Have you cleaned the throttle body?

[plowther]

I have replaced both O2 sensors

I will try cleaning the MAF.

It is a three speed automatic.

I recently replaced the air filter but I will look at it again when I clean the MAF this afternoon.

I have not cleaned the throttle body, I will have to look that up in my repair guide. Where would that be located? near the air filter?

Thanks everyone for the help so far !

well for starters you cant clean something you dont have....

Improved the performance some. There are still times that the car seems sluggish (not as bad as it once was). Any suggestions.

I also found out that there was no MAF in my model of corolla.
