Engine vibration after intake install attempt with stock unit back on
Posted 04-26-2012 at 09:16 AM by jimhimbo
I installed the K N intake and ran into problems with stripping a screw; now with the stock unit back on there were very noticeable vibrations transferring from the engine--to doors when opened driver seat especially leg area. this happens only at idle when rpms come down. in other words turn it on, and in a few moments lots of pulsation/vibration in cabin! why does this happen? only thing I can think is that something got messed up with MAF or the connector to the MAF--I didn't drop the MAF or anything and was careful...this has happened before a year ago when i installed a weapon R intake and removed due to vibrations with the intake installed; but it wasn't secured properly due to an inability for the supplied mounting bracket to reach anything to clamp it down with...in any case--what could be causing this vibration?

If you had disconnected the battery during the install, then the ECU has been reset and is back in learn mode. You need to drive for about 20 minutes or so for the ECU to relearn.
My idle drops to about 300rpm after every battery disconnect.
If you didn't disconnect the battery, then I don't know what the issue is.Posted 05-01-2012 at 08:45 AM by WeeYari
