Hi, have been making little progress with this issue and been trawling the internet for solutions - thought I'd try here!
My 55 plate Accord ctdi (100k) has very little power 1300 - 2500rpm. Beautiful turbo rush above that (perhaps even feels more than 140bhp). Throttle position does make a difference. You can gently accelerate through the flat spot. Flooring the throttle from idle means that it doesnt pick up after 2500rpm as if you gently accelorate through the flat spot/area (and it takes an age to get from 1500 to 2000rpm)! Light throttle upto about 1500rpm feels fairly normal.
Going back to the beginning for a moment - Car was in limp mode and engine management light on. Performance upto 2000rpm was perfect, but didnt rev above that - usually. Occasionally did and reved normally with light off. Took it to garage and they diagnosed egr valve restricted flow. suggested dealer only part at £500. But thought I'd have a go at the egr aerosol cleaner first. Have taken most of the egr ***embly off and sprayed with wd40 and cleaned all gunk off (alot). Sprayed a can of the ege cleaner through the MAF intake and filled the tank with Shell V Power including an injector cleaner (not BF244) mix in the tank. Changed the oil for fully synthetic 10- 40, new oil filter and fuel filter... Result? No, still flat at around 1500rpm, maybe slightly better - however engine management light now off. Sound improved a bit but still quite tappety/rattly.
Ive looked at the DIY EGR clean on this web site (slightly different model), but just wondering if I need to do more cleaning?? The fuel tank has only gone half way through its mix and I may not have got to all the gunk inside the egr passageways. could injectors be blocked or even the pre CAT filter or the CAT itself? Will the V Power/cleaner mix clean those parts out with another tank??
Any pointers gratefully rec'd, Many thanks!
