Hello everyone!
Greetings from Lithuania
I have a mistery with my Accord 2004 2.2, maybe you all will help me to solve it because I don't know where else to look
Problem is that car has almost no boost from turbo till 2.5k revs when it really kicks in. In rare occasions I feel it kicking in earlier (especially in 3rd gear or when going uphill).
Things was done:
Replaced turbo - no difference.
Fuel filter (yes, correct one) - no difference.
Took it to local remapper:
EGR Off - Car got much better on low revs, much much smoother to drive, less fuel consumption, not struggling to accept the throttle anymore. After thst car basically was able to drive again.
Also he tested it on Dyno and told me that turbo only starting to boost at 2.5 and its full boost is on 3.5k rpms. It managed to squeeze the original HP without remaps, just egr off. He also told me that normally it should start to boost at a little bit more that 2k and reach full boost on 2.5k (showed me the graphs of the other hondas with same engine).
He diagnosed that a lot of problems should be in EVR valve.
So..
Things I did:
Replaced EVR - car got better, from this moment I sometimes feel boost earlier. Car lacks of power in second gear.
Replaced IMRC, few different ones, still don't understand if there is any difference in that (still trying to figure it out).
Tried replacing MAP and MAF, no difference (remap guy told me that were ok also).
Tried replacing air intake shuttle position sensor (dont know how it is called), because I had few laying around, no difference also.
Checks catalysts - all good.
So guys, I don't even know where to look at. The donor car I took turbo was driving excellent. Although it was facelift model (is there any turbo differences?).
Maybe you have some ideas or suggestions?
Also Worth to mention is that I have put six gear gearbox from facelift because I had to replace the clutch but had gearbox laying around so figured why not? Now it is much better on highways
Also worth to mentions is that car doesn't smoke, no blue, black, white smokes.
Waiting for your opinions guys, read a lot of threads here but still I am where I am.
Many thanks!!!
