This may seem like a stupid question but here goes...I have a 88 TII,and with the engine warm I'm only seeing 16-18in, is that cool seems kinda low to me. engine is stock j-spec engine with who knows how many miles, I've checked for leaks ect. let me know what are you guys seeing...thanks

 

anyone?

 

Looks good, I only see @ 15 at idle

 

Nice,I looked in the fsm, and couldn't find any specs...engine runs great just wanted to know as I just put in some larger injectors replaced gromets and put in new o-rings,after replacing the upper and lower manifold gaskets, just thought it might bring up my vac numbers, but i saw no change. Thanks for the info,it's nice to have something more to go on than my guess, that the numbers are ok.
