Hi All, first time post and sadly it's one trying to find advice on a problem with my daily runner!
I have a 2004 Accord CDTi which has developed a judder / vibration under acceleration. So bit of back history, the car has a full service history, however as it had gone over the 100k mark I decided to start doing some DIY (Destory It Yourself) servicing. Now I am not a virgin to working on cars but this was my first time working on the Accord, I am a Honda Del Sol nut and spend many a weekend working on my B series and D series Sol's.
Anyway I got a service kit from my local motor factor and fitted it all to the car (102,072 miles), on the first drive post the service I took the car for a spin and found the drive was very flat. Under acceleration the car would lose power and then start to cut out, then the EML came on and the car went into limp mode. After plugging in my computer the fault was low fuel pressure, hall marks of a dodgy replacement fuel filter. Anyway I headed down to Honda and after picking my jaw up from the floor walked out of the dealer with a genuine fuel filter. I fitted it to the car and the issue with the power lose disappeared and the car was running a dream, seemed to have a lot more power low down.
After 300 miles the car then developed a mild vibration in 3rd and 4th gear under acceleration between 2,000 - 4,000 rpm, this soon developed into a heavy vibration / heavy judder in 3rd and 4th felt through the steering wheel as well as my seat. The whole car felt like it was trying to shake itself apart, passengers notice immediately the shake. But at the point did the EML come on. There was a feeling of a slight loss in power but not a massive amount.
So my next step was to try bleeding the fuel filter, which I did, this had no effect on the issue.
So the car drives now with no faults recorded on the ECU, my MPG return is 55-59 and I am getting 650-700 miles out of a tank. If I keep the car below 2,000 rpm I have no vibration or judder, as soon as I use 3rd or 4th gear above 2,000rpm the engine feels like it is starting to shake itself apart. This shake gets worse and worse from 2,000 rpm up to 3,800 rpm where it then stops. 3,800 rpm to red line it does not vibrate! Also note I do not notice the vibration / judder in 1st or 2nd gear.
There is a slight vibration in 5th gear above 2,000 rpm but it is nothing compared to the shake in 3rd or 4th. I am puzzled to what it could be, I thinking possible EGR issue? But have also read about driveshaft and/or dual mass flywheels to be a cause of vibration? I have now hit 110,803 miles and have lived with keeping the car below 2,000rpm.
Before I start pulling my hair out pulling the car apart has anyone experience this kind of issue? I have tried looking through the forum history for other people's posts but the symptoms I have seem slightly different.
The only other background history to the car is Honda replaced the Alternator and fitted a modified / updated pulley tensioner / updated belt for free back in November 2014 due to my alternator failing. Car had 95k on clock and was 10 years old but I was very lucky and Honda paid for it all to be sorted.
Any help or advice please!
