Hello all this is a strange problem and one which my garage seems to be clueless about.

I got some new spark plugs for my Voyager from local auto shop. The correct plugs were determined by the vehicles chassis number. I replaced the old spark plugs with the new ones, a simple job I have done numerous times on various vehicles with no problems. However with the new spark plugs in the car now will not idle, it starts and runs but as soon as I take my door off the gas the engine stops. Thinking maybe the new plugs were not the correct ones I took out the new plugs and out the old ones back in. Still the problem remains, the car will not idle.

Does any one know or have any idea what the cause may be and now or rectify it?

Many thanks.

 

I'll centre around the coil pack and leads as these are what you moved on changing the plugs. Even something to do with the harness around the engine. Was the tick over erratic, jerky running, before the plug change as to coil pack.

 

Thanks for your reply Goggs. The tick over wasn't erratic before the plug change but it ran really rough and jerky under acceleration.

 

Certainly pointing to coil pack or leed...Then there's crank/cam sensor but more like wiring harness.
