Heya guys, its been a while XD

umm ive had a small issue with my engine thumping! it particularly like to do it with the ac on at stoplights! it randomly does it and i think maybe the idle is to low? but it sometimes does it when the ac isnt on, though this is more rare. also when getting to to speed around 60 mph the rpm at 2 and half it thumps and jerks a lil bit? maybe related not sure. Any ideas? XDD

i have the 05 3.5 L v6 4x4 gls XD

60,000 mile or there abouts ? Change the plugs and wires... don't skimp on the plugs, to big a PIA to do, so use the NGK platinum as equipped, or upgrade to NGK Iridium.

Look at the coil body for grey/white spot too.. MIL illuminated ? Codes ?

Program #82 for throttle response, just programmed 1 today, didn't see A/T program on my menu when in ECU upgrade screen..

i just passed 85k miles.. X3 and the engine light has been on for me over a year now, it just randomly turns on and off. I have a dead oxygen sensor and i haven't had the cash to get it repaired. I haven't had any trouble out of it so the sensor hasn't been high on my priority list.
