Did you clean it properly both sides, fully disconnect it? You need to do a Throttle Body Re-learn.

U have a vacuum leak from the brake booster or one of the vacuum pipes

Check fuel pressure, check timing belt, check for ignition spark. Run a fault code test with a code reader.

well, you never said which engine,
we can not guess engines 99% of time. (and for sure outside uSA)
this is a USA site, so where are you?
open hood in uSA look up, see EPA sticker there, engine name is there, (sure is here)

here is the lineup
1.8 L 1ZZ-FE I4 (132hp)
2.0 L 1AZ-FSE I4 (152hp) 2.0 L 3S-GTE I4 Turbo (260hp)

google your engine, name see real names above.
googe them and i promise a zillion hits.

even a better question is "IS MY ENGINE Interference or NOT?"
always #1 , and for good cause, ASK.

all answers USA as this is a USA forum.

have the OBD read for fault codes
