Hi guys,
I have a 2004 (54) fiat doblo cargo 1.9jtd 8v and have a judder (kangaroo effect) between 1500rpm-2000rpm on light acceleration and more apparent in 2nd and 3rd gear but very slight 4th and never in 1st or 5th, to get past this judder i either ease off or accelerate harder and its fine, plenty of power, boosts fine and drives spot on except this little judder, judders more when warm put apparent when cold also.
I believe i have tried everything to resolve the problem and to be honest im now at a dead end. I have no lights on the dash and no error codes stored, the things iv done and tried......
New dmf and clutch
New gearbox oil
New airfilter
New fuel filter
New rear engine mount
New crank pulley and tensioner
New battery
EGR blanked off
Cleaned cam sensor
Cleaned crank sensor
Cleaned maf sensor
Cleaned map sensor
Cleaned boost solenoid
Cleaned over boost valve
Checked turbo actuator movement
Back leak test, all equal measures.
Checked all vacuum pipes for leaks
Checked all intercooler piping
Cleaned and checked TPS.
Removed ever electrical connector and cleaned in the engine bay.
Ran 2 bottles of redex as per instructions.
Iv drove with the MAF unplugged and judder is still there and made no difference at all.
This is my first ever post on a forum so please go gentle if i have posted in the wrong thread or missed any info lol Any help or advice would would be great to get be a step closer to resolving this issue.
Thanks
