Hey Guys,

Last week I posted the problems with my E-320. Here's what I wrote:

Here are the symptoms:

random ticking from underneath passenger side of dash
slight engine surges that coincide with the ticking noises
abrupt hesitation upon hard acceleration
cruise control fails to work

These symptoms are much more noticable until the engine has been running for several minutes-- even after it's warmed up. Once past a certain stage, the clicking noise goes away along with all the other symptoms and everything runs fine.

Also, but not necessarily related: sometimes when I arrive at my destination and place the gear shifter in any postion other than D, the dash lights and center consol lights flash rapidly. Maybe that's related?

Also:

When cold, the engine regularly takes three turns of the key to start. There's no cranking involved, it just takes three times before it "connects". This began happening before replacing the OVP and is still happening.


Question:

My mechanic suggests changing some little thingy that tells the engine how much gas to mix when cold. It has something to do with the radiator or coolant, I believe. Could that be the culprit?

Can I rule out the throttle actuator and wiring harness since the symptoms are not present all the time?

Thanks again for any help!
