Post subject:  Very strange start up...
Dear Lost friends.. Or better friends on Lost ...
Today I took my kj and it started perfectly... After let's say 15km of happy driving :JEEPIN: I parked in order to do some shopping.
Once finished I ignited the engine back, and it started to vibrate , I did not realise it ..I drove 2/300meters but the car had no power ... Specially on the third gear.. Like the engine was running with three cylinder...very strange. :dizzy:
I had the same issue last year (happened only once ).
After having switched off and restart the car the issue disappeared...
does already someone encountered the same problem? Witch kind of issue is ? Injectors? Electrical problem? Both??? :juggle:
Thank you for more than a welcome advise... I am very concerned :ALONE: ... Thank you again... :D

Sounds like limp mode. Check for air in the fuel system. When did you last replace your fuel filter?

Well 15k km ago... What is strange that the car continue in this way for a long time till I perform a restart ... Like Microsoft stuff basically lol.... :seuss:

Sounds like the beginning of 'sensor confusion'. This happens when the ECU sees signals from a sensor which are out of spec with the expected values, it then puts the engine into limp mode to protect it. Sensors deteriourate over time and factors such as age (ie prolonged heat soak, and high mileage). The camshaft and crank sensors are the ones that are most likely to suffer sensor failure because they plug into the head and block - which obviously gets very hot. Transmission sensors, and the MAF are much less likely to have this sort of problem. The fact that it is ok after you turn it off for awhile, or early in the day, points to heat influencing the sensor. There are sensor testing suggestions in the service manual, and I think there was someone on LOST that had a test that could be done with a multimetre.

That happens to my wife's about every 5000 miles. We have just learned to shut it off and restart it until it runs right, usually takes 3 starts then it will run fine for months. It started 30,000 miles ago. I know it is not a fuel issue because all I do to fix it is restart it.

I agree it sounds like an intermittant limp mode although a new fuel filter or at least a check for air in the fuel lines is worth the effort. Otherwise drop by someplace that has a code reader and see if you have any helpful codes stored.

Thank you ... Actually the filter has 20k. Km .. I will change it and I will take advantage to change the GP behind the filter ...winter is coming :roll: and last year had failures on the first two... Still wondering how to change the one behind the EGR... :|

To do the #3 plug you need to remove the aluminum intake elbow from the cam cover.

I would love to have a tutorial how to do it step by step...I know exactly the first step : 1)take half day off :wink: , 2).....
There are some interesting threads on LOST.
I consider myself pretty handy but really .... the description w/o pics make me really puzzling.... :dizzy:

A' propos of recent posts, this might also be a stuck open recirc ball in the injector....

This might be related to the fact that I did not use it a lot recently (had very sunny days -> Vespa) . I will change the fuel filter.....
What is exactly the recirc ball in the injector ? Do you have the link of the post maybe....? :juggle:
