go to autozone.com upper left current vehicle. choose car, repair info, vehicle repair guides, engine electrical and firing orders.
Here is a diagram.
firing order is stamped on the intake manifold
Check the ignition coils and the crank sensor for the Yukon. Either one of these could be bad and cause the problem.
You could go to autozone.com under repair info then specifications to look up firing order.
In a Chiltons automotive book for the sunbird which I believe is the same for the cavalier for the same year. You could either buy one from an auto parts store for about $20-$30 or check one out from a public library if they stock it, (they should).
have u checked spark plug wires, ignition coils, timing,spark plugs or had it hooked to a reader?
The spark plug firing order is ( 1 - 3 - 7 - 2 - 6 - 5 - 4 - 8 ) It has the Coil On Plug ( C.O.P. ) ignition system with ( 8 ) individual coils The engine cylinder locations are numbered : firewall 4 - 8 3 - 7 2 - 6 1 - 5 front of Ford F-150
1-3-7-2-6-5-4-8 Click the link for a diagram.
Yes, and if you had listed the make, model, year, and engine size I could provide one. But you listed none of this information so my hands are tied.
this is the best i could do, hope it works looking at the motor the coil pack is numbered (left/front2back)1423 (right/front2back)3241 the cylinder is numbered (front2back)1234 the firing order is 1342
You will get a miss fire. This could include but not limited to a check engine light for random cylinder miss-fire. U will more than likely damage the sparkplugs if not changed to the correct firing order and could damage the ignition coils. I hope this helps and for the correct firing order u should get a print out from autozone its free.
Could be several things...It could be low on refridgerant or the coils could be dirty. Check the coils first as this is something you can do your self.
