Whats happening?!! 147 16v jtd 2003
Firstly I would like to thank all Alfa owners who post on advice and tips on forums as one month ago I new nothing and through doing a bit of research I have saved myself plenty of cash by following the advice i hove found.
My problems began with a leaking injector seal, It looked like it had been leaking for some time as it had that hard black coal to the top of the injector. At the same time i decided to sort out the tough gear selection so changed the top hat bushes on the gear selector which involved taking out the battery tray etc...
With the injector seal sorted I found that the car was juddering had no power and the engine Motor Control System Failure message came on. After a 30 mile trip constantly having to change down to get any power and black smoke coming out the back. I returned home. I then pushed and wiggled various wires around the engine bay. I then found the MCSF sensor turned off. The black smoke was still there.
I then cleaned out the EGR and MAF that didn't make any difference. The MPG was down to 48 MPG from 55MPG and black smoke on acceleration. I used a forte injector cleaner which had no effect.
I then took it on a 500 mile trip to london and back. Black smoke on acceleration, power was ok fuel consumption was around 50mpg.
I then decided that it must have been the injector so took it out stripped it down to its parts, cleaned it and then put it back in.
It was then I found the 4cm split in the upper turbo hose about 5cm away from the engine. I'm a tight git so rather than buying a new one I have used some really good rubber repair tape and supported it with cable ties.
I then started the car and found that it was juddering when it was idling. Upon acceleration it has a lack of power and judders all the way up the gears. It feels similar to when your in the wrong gear on a hill. On a plus side no black smoke!
So what has happened? Should I clean out the MAF and EGR again as they may be dirty as the inside of the turbo hose was caked in black oily s**t.
I have bought a cable to plug into the ECU but it doesn't show any new errors?
