Intake manifold vacuum check valve and leaky vacuum hose replaced. Also swapped out a newer FPRegulator due to gas odor in the vacuum line and set of used injectors with new o-rings just because. I think todays repairs made a big difference but have a lingering rough idle when compared to my good running 93 240.
Tomorrow I will replace the intake manifold gasket although I can see no evidence it is bad. Admittedly it is very hard to see the lower side of #3 and 4 cylinders.
Any other suggestions for a rough idle but otherwise seems to run fine are appreciated.
Thanks
Dan
