Hello

I am having a problem with 1990 fwd 2,5L iron duke. It has serious miss when cold, gets better when warms up but still misses. Never completly dies, always starts.
It is distibutorless system, where there are sensor, chip and coils on the side of an engine block. What could cause it, what part to swap out first?
I have already changed plugs and wires without any sign of diference, and it doesn't give codes.

Thanks

I haven't tested it yet.
So you think that it is not ignition problem?

how many coils do you have? i would not recomend it but i would put my hand on the coils as the engine is running to see if i get zapped. i would also touch the exhaust manifold at the ports as soon as the engine is started dead cold to see if there is a cold cylinder.

70 L camino, grampa engine, g-force 5 spd, road rage suspension. Pray first before all else fails.
