Cruisers #13 seems a little extreme to me. Maybe I have yet another thing to learn there! The deal is, since the puter' advances the spark, but nothing in the dizzy moves, it's set with the rotor just ahead (a tad), of the electrode in the cap. (static, at TDC) This so when the ECU advances the spark timing the rotor is still close enough to the electrode for the spark to easily jump.
The two piece crank pulley can slip, moving the timing mark. That's always fun.
Once on a Dodge "K" car, I loosened the header pipe to manifold bolts so exhaust could leak there. Immediately I new I had a clogged CAT, since full power came back.
Just rambling
Balancer shift, I'll double check tdc when I check the timing chain.
I was a mechanic during the dreaded K car time! It always amazed me that such a miserable, POS car saved Chrysler from bankruptcy!
DF Flinstone, I think your on to something. Checked the timing chain play today and I could turn the crank almost 1/8th of a turn b4 the rotor moved! And the balancer bolt is loose! Looks like a timing chain is in my future, might be the clattering I hear when I start it cold. Might just drop the pan and put a oil pump in it to. Any suggestions on brand and/or type of chain set? Oil pump? Any tips for making the job easier? Doesn't look to tough tho:-) may be awhile but I'll post the results as soon as I'm finished. Keep your fingers crossed!
Found another part of the power problem. I had a ecu from an '87 not a '90! Swapped out for the proper one and it seems to have made quite a difference🙂. Short test drive and then a minivan cut me off😡!
Looks like Farmers will be paying for my timing chain and oil pump! Lol!
