my car has an abnormal idle.it will go from about 400 rpm to 1200 then keep in that cycle.the timing is perfect,it has a new distributor,new plugs,new fuel filter,and a new iac valve.it is running wierd and the engine studders when heavy on the gas or at low rpm's. i bought a new iac valve and i was taking the vacuum hoses off the bottom and anti-freeze came out.im not a mechanic im a body man.is there supposed to be anti freeze in those lines or am i in trouble.if so i appreciate any help in solving the problem

where would i get the piece of heater system for the throttle body,and how much would it run me? thanks for the reply

Its built into the idle control valve nothing to buy

Its not so much a heater, more of a temp unit for idle control

I definitly recommend taking all that off and cleaning it. All the stuff off the Intake mani around the TB, I had some problems so i took mine apart and cleaned it, corroded like crazy, and it idled much better afterwards.

i put on the new iac vavle that i ordered and there was no change in the idle or anything.then i put the stock one back on and still the same thing.before i put it back on i cleaned it out with carb cleaner.i dont kno what else to do.except a motor change.haha.
