after putting a bunch of stuff into my 1990 2.2 tbi i had a guy tell me last night my problem may infact be a leaking gasket at the thorttle body...fluxuating idle and bogging down at a rapid acceleration are the symptoms..other wise if i take off like a little old lady it runs just fine...is this gasket any big deal to replace?..i called a local shop yesterday and they quoted around 120 bucks...thanks for any reply

I'm pretty sure the 2.2 doesn't have a throttle body gasket since the throttle body is molded into the upper intake/plenum. You may have a clogged fuel filter or air filter, low fuel pressure, a torque converter clutch solenoid that is staying locked...clogged exhaust? On rapid acceleration does it continue to bog until you release the accelerator, or is it just a temporary thing? Check for a vacuum leak (broken, cracked hose). It also may be a number of different sensors or even PCV valve. Sorry I can't be more specific, I haven't worked with the 2.2.

just replaced the pvc..new 02 ..cleaned the egr..new air filter...had intake gasket replaced..new ecm installed..new mas..new coolant temp sensor...new plugs...wire's...yup...just going from a full stop like if your at a light or at a slight roll and you put the gas to the floor fast is when it bogs..and pop's at the throttle body..once i back off and depress the accelerator sllower it runs great..,,fuel pressure is good...car runs fine otherwise..can clip along the e way at 85 no problem. and even hit passing gear at full power . i just use this to get to and from work so in the worst case i can live with it but i rather not..overdrive was shot so i disconnected that and just recently had the the tranny flushed and filled....thanks for the advice

U may have a pluged injector filter or a injector thats taking a crap. seen a few of 2.0 injectors just not spray right when they get older.. also check your tps sensor to make shur its reading correctly..

Coils/ignition module is most likely taking a dump on you.

okay ..thanks for the replies i will check the easy 1st...if i spray at the base of the throttle body at the intake with starting fluid and here a rise in the rpm i think that should tell me if the gasket is bad wouldnt ya think?
