Stooging the Throttle Plate Balance?

No, that first one is off by a couple inches. The needle is not the same as the other three.

 

In the instructions, it shows you how to remove the faceplate, and turn the silver calibration screw on the front... (I had to do this with mine).

Were you experiencing any symptoms prior to balancing? This crossed my radar recently as well so was also curious about the process. Thanks for the info. Also local to you if having another car to measure is in anyway helpful.

 

The idle is not quite as smooth as other 355s. Although, I am aware that the 355 does have a lumpy idle on many cars.

 

Thanks, I'm getting ready to do an overhaul of my intake system and this would be part of it. Having done it previously to other cars, the difference was significant and well worth the effort.

 

Mitchell, say hi to everyone for me
The butterflys leak like poop if you drive the car at the shaft
Cant remember I think jag v12 ones fit with a slight trimming. I did a spare set I have here and did not install it yet
I absolutely HATE when the intake is not 1000% correct. It really helps with the ecu to be happy.

Need a sequential gear box that will fit in a 348-355 if you run across one

 

Pretty sure your aware of the Hewland, spendy though.

To close this off. I got a TB calibration step from Sam Fung. After clearing the CEL, performing the TB calibration, the engine fired up and immediately runs better right off the push button Start. Over 100 miles now and no more CEL.

That must be the reason.

 

Is this car a 2.7 or 5.2? So you mention you had a CEL and poor idle, and the TB calibration procedure corrected both issues? Thanks.

 

Yuup have the same ones, work great
