I have been having some throttle issues with my car.
When I bought it an Autoshield report said "shows early signs of wear" and at 55,000 miles on the original TB and pedal pot, I thought I best change both.
The car ran fine apart from a mildly wavering throttle when you back off in traffic (its an auto btw)
So trying to grab things with both hands and prevent future issues I sent my TB off to Maserati Shed to refurbished/made contactless, and also ordered a contactless pedal pot from davy.
The issue I am having is when I start the car, sometimes it revs to just over 2000rpm constantly. It also still wavers a bit when backing off at low speed.
This happens both with my original pedal pot, and the Davey one - so I think can probably rule out the Davey pedal pot.
My car was at Grimaldi having the geometry set, and Aux tensioners and belts changed etc, general check over, replace brake pedal switch etc.
They did a smoke test and no leaks found, also no visible issues with vacuum or boost hoses that I can see.
The car had all o rings to the plenum replaced just under 2 years ago and less than 3,000 miles ago by Autoshield when it was prepped for sale by Richard Grace.
So, a bit mystified really.
My best bet it that the throttle body is actually sticking - when I tap it with the handle of a screwdriver it seems to go back to a normal idle.
I can try speaking to Maserati shed, but suspect he will be suspicious and presume my car has other issues.
Any ideas guys???
