fouled plugs |
|
|
My son's 90 Lumina with a 3.1 engine has developed a miss. We pulled
all the plugs and found #3 and #5 plugs were carboned up. Replaced the
plugs along with sparkplug wires and it still has the miss. Normally I
would do a compression check next, however my compression tester is
unavailable for a few days. Is there anything else I can check while I
wait for my tester?
Thanks for your help

1. Is only one cylinder missing?
2. Are multiple cylinders missing?
3. Are random cylinders missing?

Have you checked for spark? |

A cheap spark plug tester can be very helpful in wringing out problems like
this.
If you dont have equivalent spark on the fouling plugs, then clearly you
have to
back up into the ignition system
#3 and #5 are next to each other, arent they? |
