k i have a 98 gsr supercharged 440 rc injecters some other stff but enyway nn it putter. when warm it just idle real low an rough. when warm driving it runs fine till i slow to a stop then rpm when put in to nutrall will almost cut off on me has cut of a few times dont no if its a vacume leak or bad injecters this problem started after i took injecters out put stock in an ecu to get through emissions started when i put 440 injecters back in but droped ful rail support as well when putting them in so think i pulled a vac loosewhen lookin for suport please hep if can its killin me loosin my mind ps also replaced spark plugs did nothing

 

for one, please type in a language that can be read easily and clearly... "stff but enyway nn it putter"?

My advice here would be to check the timing belt, since the supercharger is a belt driven FI system it could be causing this problem ... also since you just swapped out all those parts to pass emissions and then put them back on afterward, in the flurry of torquing and socketing there could be a loose connection somewhere in the head or the fuel system that could be killing your idle.

In all, i would suggest to check your timing and make sure everything you re-installed after your emissions check is torqued to its proper spec. Then if that doesn't work curse me for making you do unessecary work gl

 

Well for someone who is great at spelling and grammar you sure don't know your cars because it has nothing to do with the timing belt or haste in re-assembling, that is a certainty. The supercharger's belt was untouched in the installation process so what makes you think the timing belt would be the cause of the car's sputtering / misfire? Everything that was taken out and reassembled had nothing to do with the timing. I know that the problem has to do with either a vacuum line, an o-ring on the injector or a bad injector. Any applicable advice will be sufficient next time and I promise not to be drunk next time I post things here. I was just upset and needed a little advice.

 

could also possibly be a bad TPS sensor or IACV? If not my guess would be vacuum leak.
