Ever since I bought my car it has always ran a bit odd. Like when you start its really bogged. It will be like wuh wuh wuff whuff whuff even when you get to street lights reds I mean it will wanna stall. I mean dont get me wrong its reliable but I dont get it. I replaced the EGR valve, O2, Map Sensor, plugs. The wires are fine, so is the cap. Would you all suppose its the timing, cat, or fuel filter. I dont even know how to check timing.

is it the 4.3?? i thought it may be since you are mentioning the sensors. i think the timing may be a place to start

Many autoparts stores have scantools which they will let you plug in to see what the computer tells you.

Get a timing light and follow the manual. It's actually really simple.

Setting the timing if that's a problem... less simple.
