at idle its at 20 lbs vacuum. cruising in gear off throttle at 28 lbs vacuum. hold rpms up slightly while stopped and it drops slightly below 20 when i let off gas then goes back to 20. i dont know if its normal for the car. i posted a day ago n the reply i got was pretty childish.. i just wanna yes or no answer as to if this is normal for a lsj.. i dont really need direction for finding the issue, just need to know if there is a issue. i appreciate any ideas on what it could be but am not counting on it. thanks
