So i have to clean the injectors , i will do that.
What about the problem with the horn?
Thank you for your help.

Is the engines oil reservoir topped up all the way?

It's about half full.
I recieved an email an hour ago and i got an answer about the horn problem.
The problem occured when i made the compression test.Some optimax models when you crank the engine with the kill switch to OFF they built up and trap electricity in the starters solinoid and then when you crank the engine with killswitch to ON this current travels through the 14 pin harness into the ECM and shorts the horn's circuit.
That' why the horn sounds all the time.
Solution? a new ECM .

Now that does sound good.....

Good news, Mercury will send me a new ECM for free even though the engine's guaranty expired 6 months ago!!!

Didn't you say a while back the ECM was flashed by someone?

[kostas74]

Yes i did.
Is that going to be a problem in any way?

Usually if a coil on a opti is bad you will know by the potting melting out I would ckeck you feul/air psi should be 8o air an 90 fuel , if there reading the sam it would mean you have a torn diapgham in the tracker valve or fuel regulater that will cause them to run lean, an checking the coils with a meter will only tells you its not shorted out , find some one with a ddt to do a miss fire test then fire each on injector the tips some times get stuck you will know because it will not click as loud as the other good cylinders , hope that helps .

I did a check with the DDT and everything seems to be ok at least electrically.
The only thing i haven't checked yet is the fuel/air pressure.
Thank you.
