Re: Troubleshooting Hard hot Start problem narrowed. 865ktq

Please post any findings on this as my 90 200 has the same problem,
I've replaced everything short of the regulator, injectors, fuel distributor and

freq-valve. It looks like I may bring it into the shop soon. Mmechanic here says

he's a CIS guru. If and when I do this I'll post what the problem was, however
I do think it is the regulator.
