Hello all,...i have a Metro here that i just recently rebuilt, has about 5,700 miles on new engine now.
Its been running w/o issue, in the last few days i have noticed a small, to pretty bad misfire upon
taking off from a stop light etc,
only lasts about half a second or one second, then clears up...
no misfires when cruising at speed.
Just on take off...
I knew it was in need of a tune up soon, so i did plugs, oil, oil filter air filter,
cap & rotor,...none of my removed used parts gave indications of problems.
Plug wires are about 4.5 mo old,
so didn't do those, ill check the boots out to be sure....
On a hot day it seemed more frequent, and pronounced.
It was not overheating, fan was cycling as it should.
It usually stays under half on the temp gauge,
i took it for a 15 mile ride today and only noticed a very slight miss on take off
once or twice, nothing since.
Im thinking the coil is possibly going away, its likely the original.
OR, suspecting possibly the cam / crank sensor in distributor???
Any thoughts or tips would be greatly appreciated,
