the van began minor irregular jerking while traveling at highway speeds as if ignition were missing in an irregular pattern. We then noticed that the engine seemed to be idling fast. Mechanic replaced the throttle barrel gasket which corrected the fast idle and the jerking seemed to be cured also,but on the first trip of some distance, the jerk began at about 30 miles out and continued to randomly occur for the 400 mile trip
throttle body running lean with gasket leak. dying out when put into gear. it was fixed at $500
It stalls when coming to a stop. Only occurs when the van is locked up. One mechanic looked and says that it is caused by air leaks in the throttlebody. Can be fixed by replacing gaskets.
Hi idol bucking and stalling
