Hello Guys, I have a throttle problem in my 2004 AP1,yes AP1 because it's a Euro version, still come with an F20C engine until this day but with the new generation body and everything. Anyway, the problem is that, after 5-10 minutes or so of driving, I get a weird feel of lack of gaz getting pumped into the engine as if the car is about to turn off, or like a trash in the gaz, then I pump the throttle a little, it goes away, and everything goes back to fine and smooth?!??!? This happens almost every 5 min for like couple of seconds. I'm sure it's not gaz type or gaz quality, I've tried different stations, and still the problem exists, and not consistent that's the weird thing. No Engine Check light is on.

Any idea?

 

Do some fairly standard maintenance:

1) check/replace air filter

2) clean throttle body including the air passage to the MAP

3) clean the IAC

Look in the FAQ or search under the hood for instructions on how to do 2 & 3.

 

Check the TPS and MAP sensors.

 

I changed the Air Filter and I put a K&N one, but the problem still exist. I also put fuel cleaner everytime I fill up gaz. I'm trying to see if anyone had this problem before. I am planning to go check it, but the dealer in my country is very expensive, and the small shops do not have advanced machines.
