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 Dale
