"trick" spark plugs are just that. You can only make one spark at a time so therefore regardless of the number of contacts, that's all you get...one spark. Put the right ones back in and make sure you have the right wires on the right plugs.Also make sure you didn't disconnect any vacuum hoses while you were working!

I have 1995 chevy lumina with the3100 engine. It starts fine but idle is rough and has loss of power and smells like unburnt gas.


How long since overall tune-up? Any applicable trouble codes?
The basics for a rough idle, check for a leak of some kind, fuel--egr--vacuum, something of that nature. Does it run ok off-idle?

What would cause 93 chevy c1500 rough idle smells of excess gas at exhaust


Does the truck seem fine when you first start it & then acts up when it reaches operating temp?
That would lead me to look at my oxygen sensor, a bad sensor can cause the truck to run "rich" which would explain the fuel smell in the exhaust.

Changing harmonic balancer


Nope! Why don't you give the mechanic a tune to see if it's running rough because of lean mixture, fail ignition coils, worn spark plugs....could be one of those things. Because when yours is rough at idle, it means the mixture is not right, more likely be lean or one or more cylinders not igniting properly. Got nothing to do with harmonic balancer. But do check motor mount for cracks, but faulty mounts only give you excessive movement that you can really feel it KICKS when you change from P - R - D.

2001 Chevy venture intermittently running rough.


Check air filter. Check for any vacuum leaks. Check condition of plug wires. Were new plugs pre-gapped? If not, make sure the spark gap is correct for your vehicle.

Running "rough"


I had the same issue with my venture. It turned out to be the number 5 plug wire, backside of engine ended up breaking out of the plug carrier and burning in half on the manifold. Your best bet is to trace all the wires to start off with and change the plugs. If that doesn't help, it may be internal. Good luck
