Hello all,
The Story:
First I run on wvo and I want to say that its not the problem but it might be related as some crud might have been dislodge in the IP.
I first put a bit of ATF in the tank to clean the injectors/ pump etc... as the old tale says.
On the same time I emptied the CAT.
Shortly after the car was not as swiftly as it use to be? It was odd...
All pointed to the cat removal, lack of back pressure etc... I was gutted ( like the cat) as I thought it would have been better for the engine.
Anyway, after awhile, I got a spare CAT reinstalled. To my surprise, the car was still the same, meaning, never like before...
I was again gutted...
It use to kick in strongly, now it was like a soft take off... Granny style...
I run the car on strait dino, expensive. Still the same as on wvo.
I tweaked the wastegate. Same .
I play with the advanve on the IP, up and down. No change, that was too odd, the car was the same no matter the fuel or the advance?
I injected high pressure air into the line backward, I swapped the lines fed and return, I changed the fuel filter, clean the pre filter, same... The tank strainer has been removed long ago , then this is not it.
Back on WVO, I decided that perhaps I needed to put some ATF strait into the IP, not in the tank, then I run about a litre of strait ATF.
The car went worse... Sob Sob... Now under load it can barely rev over 3000, while on park it can go over 5000.
After the ATF, I run 2 bottles of professional injector cleaners strait and left the pump sucking in this over night.
In the morning, it was the same.
I did a Molly purge pro line strait as well, reving up and down.
Same...
Then I decided to go for more ATF ( as it was the bother, I thought it might clean the blockage) but this time under load, I snuggle a bottle of ATF under the hood and went on the highway, on strait ATF I was getting highter rev, 4000+, but as a litre run fast under load it didn't last long and I had to stop on the merge. EEK!
Also all fuel lines are squeaky clean.
The bother is under load as the car studder and cannot keep up...
What I think might have happen is that the cleaning property of the ATF did dislodge some crud in the IP and now its blocking a hole or something.
I am going to try and do the delivery valves this week ( if its a dry weather)and perhaps by next week I'll remove the pump ( but this is daunting me a little, thanks to GSXR tho for all the info, really helpfull, see below)
Injection Pump Removal on OM606 for Bosch Service

Anyone has any idea?
I am thinking of getting 5 litre of atf and putt it in the tank, that should last enough to run the car on load for a wee while...
Reckon?
Thank you.
Olivier
