Keep me in the Alfa club - £50 reward.
As some of you may know I'm having a maze of issues with my 159 1.9 jtdm ti, and I'm border line about get be rid of it. Sooo I'm going to offer a £50 paypal gift reward to the person who fixes my problem ( genuine honest offer ) explaining everything that has been done and what could of led to this could take a minute so bare with me ....
0: when I purchased had new turbo and cambelt kit less than 12k ago.
1: Had a lot of EGR problems so it was on and off about 10 times to be cleaned, Finanlly gave up and brought a new pierburg unit, only to find I had damaged the threads in manifold !!
2: Replaced intake manifold and swirl actuator unit + fitted new EGR valve.
3: New fuel rail pressure sensor ( as I dropped something and walloped it by accident ).
After this the car ran perfect for 2 days approx 3 hours running, as I reversed out my drive switched to 1st gear and toed it there was a bit of a grinding/misfiring sound from the right of the engine while driving and no power and runs rough. Now also is very hard to start and sometimes fuel in intake manifold ... If you turn it off and restart it right away it's not to bad, but leave it more than 10 minutes it can turn over upto 20 times like low pressure, still runs rough, idle 850, sometimes black smoke, lack of power, no error codes.
4: Replaced fuel filter (changed nothing)
4a: Stripped and cleaned fuel system recoded injectors, ECU scan said fuel pressure desired and current is tolerable, injector or reactions all fine at 1500rpm and 2000rpm injector 4 being worst at + 1.04
While persevering with this problem I now had a noise from the left side of the engine while driving that almost brought me to a stop.
5: Finally brought multi ECU scan and cables, stored errors -EGR and Motorised throttle body (noise from left) . Cleared codes and motorised throttle body returned.
6. New magneti mirelli throttle body. Noticed Lot of fuel in intake (lots).
Now this week in this hot weather my car overheated and im hoping to the point were I haven't done major damage, no dash warnings or temp light. Noticed my cooling fans didnt cut in at over 90 tried on ecu scan to actuate and nothing. Done a full scan and got U1602 (stored) - can communication error....and P*** fuel rail high pressure sensor (stored).... Haven't driven yet o see what returns.
Still not starting properly, still running rough, coolin fan system system sudden failure ... Suicidal wondering if I've warped the head or blown the gasket ... But will check ... In the mean time £50 to anyone who suggests a fix it leading to a resolution. HARD STARTING, ROUGH RUNNING, FUEL IN MANIFOLD, COOLANT SYSTEM FAILURE, CODE U1602.
Ask for any more info ... Think out the box I've tried most things on fiat, alfa, saab forum ... But could be something I've failed to check ... No idea to stupid !!!!!!!!
Thinking caps on :/
