I'm having poor idle (not horrible, but definitely not as smooth as it should be) on my 89 LeSabre with 60k on the motor (3800 Series 1), 150k on the transmission (automatic 440-T4).
I have the following setup:
-Delco Type 2 coils (from a junkyard, but tested goo)
-Duralast 8mm plug wires from Autozone with about 15k miles on them
-NGK Iridium plugs with less than 10k on them, gapped to .060 as per factory for the 3800
-Flowmaster single in, dual out muffler
-High flow cat converter
-K&N high flow cone air filter
-good fuel pressure
So I'm thinking that I either have a weak coil or my plug wires are just too dinky to take the load of the Type 2 ignition system.
So which should I check first? Which might I consider replacing first? I'd opt for either thicker plug wires or higher output coil packs.
Or is there something I should check?
Thanks for suggestions :)
