So after my catch up maintenance I took a 50 mile drive today. I'm experiencing a hesitation just off idle and a little pulsing at minimal throttle input. It picks up with just a tiny bit more throttle. I set the butterflys at .002, and adjusted all the slack out of the throttle rods. Is this a sign of a throttle potentiometer out of adjustment or a worn contact area? Could someone give me a link in the Forum on how to adjust the TPS please.....PS. I made homemade coolant filters (temporary) and it got up to 230F before I could get home. (Took a big risk I guess) Pulled the screens and they were clogged.

RH 75% clogged

LH 90% clogged

 

Is your car fitted with the idle microswitch, if so is that adjusted correctly?

 

 

Marelli cars only. Allows closed throttle "timing strategy"

Do you need a better more permenant coolant filter solution? I'm a loud advocate for these both on old cars and my diesel work trucks.

Lots of options but my god if thats what you pull after 50 miles imagine the **** in the system...rad...heater core.

The tebfa metal strainers are junk. In line full flow servicable magnetic filteration is needed.

pm me I can link you to some stuff on that subject.

 

Here ya go.

AND

NO slack it those throttle rods is WRONG, and will cause what yo have once warmed up.

 

Thank you Grant. I do have the Idle Micro switch and adjusted it to open just after the throttle rods start to move the butterflys. Guess I have a bit of fine tuning to do.

 

Drink MORE, things always clear up the MORE you drink,

Good luck.

Time setting all that up is the key, and it does take time.

Always remember, it is 2 X 6cyl engines on a common crankcase, and with that firmly in the brain, it is soooooo simple.
