Hi, I am at my wits end trying to figure out what's causing running problems with my sierra cosy. The car is jumpy when trying to drive normally when it starts acting up and jumping the rev needle drops to 0 for a few seconds. At higher revs over 2000 the car runs fine. I have had the problem for about 4 years and tried numourus things to remedy this problem but no luck. It's driving me mad and if anyone has any ideas what could be up or had the same problems i would really appreciate help!

on the bulkhead their should be three electrical plugs in the wiring loom,try cleaning the contacts in these and see if the car improves.
