so recently i threw a timing idler tensioner pulley.. relaced them re timed the belt and now my idel fluctuates at dead stops and wen i slow down the idle drops to almost turning off. iv replced the iacv and that didnt fix the problem, changed spark plugs and wires, and a fuel filter. anyone know of any other problems or things i can do to make it idle normal again?

 

also is there any way to adjust the BISS with out the diagnostic tool?

 

if its a vacuum leak take a can of startiong fluid or carb cleaner and spray i around in the engine and see if the idle pics up if it does pick up the idle it will show you where the leak is thats not the total answer but it may help you locate the problem

 

iv tried that already and i noticed i dont have an adjusting **** for the idle. is there anything else i can check? next thing on my list is the TPS but not sure if that is the issue and i need to fix this b4 i spend more money tryin to fix an easy problem!

 

get a boost leak tester... machv.com.... that will actually tell you what is allowing air to bypass the throttle plate. If you just want to guess, check the FIAV, or get a block off plate... check the throttle shaft seals... the injector seals... the throttle body gaskets... the intake manifold gaskets... and then the vacuum lines.... if that doesn't help... I don't know what else it could be... basically check everything from the intake manifold back to the intercooler..... those are the only things that could cause an idle issue. Hope that helps brother.. have a good one.
