Question about 1999 Toyota Corolla
Posted by Anonymous on
I seen that you replace the throttle gasket, was the throttle body cleaned when this was done. I have found that when cars start to hesitate there are three main reasons( in my experience).
the air filter, The mass air flow sensor,(if you have one), And a dirty throttle body. I take a can of brake clean and clean the throttle body as far as I can into it with a brush, cleaning the back of the plates also. Spray the mass air flow sensor clean and replace the air filter. This almost always gets rid of the hesitation. One some cars it's like putting a new engine in, it can be so dramatic. Every tune up I do starts here. Once I done cleaning the parts I use part of the cleaner and spray into the throttle as the car is running. Just a note , when you clean the throttle, it will take a second or two to stat the car.
