I took my throttle body off and cleand it with a 2inch wier wheel and i marked my vacume lines but some thing is not right.ive lost my power band.It was starting at 3.5000 rpm or so and now it dont kick in till 4000rpm and some times till 5grand. there is vacume linesin the frount of the throttle body just under the the intake and theres 4 or 5 at the back of the throttle body near the block just under the egr does any one know the order the lines go in. Man this sucks i can feel the car lagging some i hate this ****.I also race a Eclipse today and won was not a challenge really was a new one. And my car is a 1991 240sx ka24de any help would be great any at all web links ,advice.And any one wanting to clean theree throttle body needs to have a little exp. i found out the hard way but i know how now. thats the only plus.

to check for vaccum leaks take a can of throttle body cleaner and spray around the throttle body and all of the vaccum lines that you removed while the car is running when you (or if you) spray across the vaccum leak the engine should smooth out for a second or two then you will know if you have a vaccum leak.

well since i checked the lines with the carb cleaner all was good but ive noticed that my car is drinking fuel like i drink beer. i meen i can watch the gas gauge going to empty Do you think that i may need a tune up.is it possiable to do my self or do i need to take it to the shop.?

you can do a tune up yourself but unless you know for a fact that a tune up is your problem i wouldn't mess with it. if i were you i would try to find a vaccum diagram and make sure that you have all the vaccum lines going to the right place. you can probably get one at your local dealership's parts counter.

also did you said you took the throttle body off? your vaccum leak (if you have one) is probably going to be were the throttle body bolts up to the intake. if your leak is there my next question is did you get a new gasket or did you use the old one? if you used the old one i recommend that you get a new one at the dealer and replace it.
