Car behaves like a bucking bronco at low speeds

[tbrewster]

While driving at slow speeds at my car behaves like a bucking bronco. No real issue if I'm just excelerating thru the gears even though I think it could be smoother.

So, is this possibly a transmission issue, throttle linkage issue, something else?

Your thoughts/inputs would be greatly appreciated.

Thanks.

Has it always been doing this or just recently? Only when cold?

[tbrewster]

It's been doing this for quite some time now and it exhibts the same behavior with the engine cold and at operating temp.

Did you pull the head off at any point? Is it backfiring into the manifold? Mine did this when the timing was 180 degrees off.

Did redo the head when I got the car due to a broken rocker arm. Doesn't seem to be backfiring tho. Perhaps I need to re-adjust my valves.

Is the idle rough or unstable? If so I'd suspect intake leaks and or a problem with the AFM. It could have a worn spot in the resistance track or a stinking vane.

Agreed, take a sniff around and find out

Found a broken hose under the throttle body. Fixed it so will just have to continue to monitor. Also had the valves readjusted so am keepin gmy fingers crossed.
