Plugs, plugs, plugs plugs Posted by Ari [Email] ![]() ![]() In Reply to: 88 9KT Hard Acceleration Hesitation, Brian, Tue, 22 May 2001 17:51:35 Members do not see ads below this line. - Help Keep This Site Online - Signup |
Sung to the tune of Monty Python's Spam Spam Spam...
Chances are that your spark plugs are gapped too big. It's harder for a spark to jump a big gap than a small one, and harder to jump a gap when the pressure is high. So if the gap is too big, the spark won't jump at high boost pressure.
Pull the plugs and check them. Replace them if they don't look good. Get a decent gapper tool and make sure the plugs are gapped to the value shown on the decal in the engine compartment. If you buy new plugs, don't assume they're gapped properly - check the gap on each one before installing it. When in doubt, stick with the exact brand and type defined in the owner's manual - if you're having ignition problems, now isn't the time to experiment. Do that when the car is running well.
Give that a try - cheap and easy, just as you asked.
