W202 Miracal

[shilzo]

you have probably noticed the posts i have been putting up about my W202 c class needing a new ecu well driving it to mc donalds today it suddenly burst back into life so what im thinking was a clogged fuel injector.

but it runs sweet as a nut now.

i cant explain it

can you.......

looks like its an intermittant fault as its back now

Your description sounds like a coil pack or HT lead going down. Is it misfiring at all?

 

[shilzo]

yea as if theres only half the ammount of power the coil packs are brand new

and yea its like 2 cylinders are missfireing

merc said the ecu wasnt reading the idle or somthing but how comes all of a sudden it sparked back to life if a chip blows it dont come back to life

 

[Dieselman]

It could be the crank sensor gone faulty then.

As you say ECU's don't generally heal so it could just be a bad connection.

Dry joints are often temperature related when it comes to ECUs, or any output device could soon cut off, if thermal contact was lost

i think im gonna just cut my losses and put the car up on ebay and start again with a newer c class (1997-1998) and hopefully i wont have the same problem glasses value the car at £2175 i paid £1600 so if i get 1600 for it again i will be happy
