Asked by Nov 07, 2016 at 12:49 PM about the 1990 Mercury Grand Marquis 4 Dr LS Sedan

Question type: Maintenance & Repair

So im trying to figure out whats wrong with the
timing on my car and i noticed when i was
checking it and i noticed when i hitch up the
inductive timing light to the #1 cylender wire its
about 180 degreese off but almost spot on for the
#7. I dont really know what to do next.

If it is 180 degrees out then you must be on the exhaust stroke instead of the compression stroke. Don't forget to unplug the spout connector when setting the base timing or you will get confused, and then plug it back in when it is set properly.

Have you had the distributor out?

I have not had it out i got the car in a trade and noticed it had a spudder and didnt seem to be running as smooth as it should so i replaced the plugs the wires and the distributor cap but it still had a spudder/ miss fire at mid to low rpm while driving so i tried advancing and retarding the timing at the distributor and noticed it was not at all close to being where it should
