If all you did was replace the plugs, and all of the above posts
do not resolve your issues, check the vaccum lines from
the back of the throttle assy to each side of your motor.
Perhaps one of them became loose/disconnected
when you were replacing the rear plugs.
Having incurred this issue myself, it was quite frustrating.
Please check items 21 thru 24 on the attached jpeg.
Also, if you still have the old plugs, verify compatibilty with new plugs you installed.
You may want to re-install the old plugs and check for your current issues.
If all fails, send me an Email.
So far as the type of plugs, everyone has their credible opinions.
I have used the Bosch+4 Platinum for many years with no issues.
Good luck,
Gerry
