bucking problem

[Jc'sLaserRs]

i just changed my spark plugs in my car gaped them just to the right specs of .028 and ive been driveing it and it bucks like when i step on the gas it used to do it with the older plugs but it just started again so what i was wondering on what would b doing this would the old spark plugs wires give it not good enough spark ### there just old bosch wires ??

Check all your intake hoses/pipes, from your MAS to your throttle body. If it's a loose pipe/clamp/hose/whatever, each time you give it gas the engine will move and separate the pipe, then the engine will stall out a little from the unmetered air, then push the pipes back together and start the process over again. Do a boost leak test while you're at it if you haven't already done so. It may not be the spark plugs at all, it sounds more like the coil pack if anything ignition related.

Like Mr Peepers said its most likely going to be a pipe somewhere that has become loose. Last time that happened to me it was just where the intake pipe coneects to the turbo.

i checked didnt find anything do u think a bad maf would cause it becuase ive heard they're known to go out and the last guy said when it went out it felt like he was going to fly through the window and he said he had the same symptoms

also check your ecu for leaky caps
