Ok I just changed my injectors out, moved my coils, and replaced all my hoses and now when I start my car the idle goes up really high and comes down really slow and if you touch the gas it does the same thing and then it will start backfiring in the throttle body and trying to cut off, anybody ever had this problem after changing the injectors?

Could have a vacuum leak in the injector o ring to manifold, or the TPS is not reading 0% throttle at idle for some reason.Ben

Ya sounds like a Vacuum leak to me, Inj Oring may not have seated correctly.
High idle with a slow drop or popping back through TB usually indicate a vacuum leak or very lean condition due to leak.As of April 2

So I guess i need to pull the throttle body back off and check the injectors again, huh. Any other solutions on what to do? thanks.Originally posted by SappySE107 View Post=Joel=Comment

Check your TPS sensor make sure it is plugged in. Make sure all the vacuum lines are plugged in too. Did you replace the injector o-rings when you replaced the injectors? Did they seat properly when you pushed the rack down? Did you replace the Upper Intake Gasket when you took everything apart and the o-ring for the coolant under the throttle? Make sure the PCV is pushed in all and also make sure the brake booster vacuum line is correct.Originally posted by jdellinger1980 View PostComment
