but isn't a recirculation valve the same as a dump valve, but instead of dumping the air to atmosphere dumping it back into the intake ?

does that small quantity of air make that much difference ?!

and how does this explain removing the battery to reset all electronics and problem is suddenly gone ?

Actually i had to do so. the rubber intake was all cracked and literally fell apart so i had to manufacture one out of aluminum. i managed to 're-do' all the other connections but i thought the dump valve wouldn't have made a difference

what do I exactly check ? isn't that sealed ?

and by 'recirculation valve' do you mean the dump valve ? mine has been removed and an atmospheric one has been placed instead. Obviously I've also used u bung on the other side.

If you are still using the EZ210K leave the battery terminal off for a longer period, say at least 20 minutes. This will fully reset the ECU. There will be a moment the event reoccurs. Note the conditions. It will probably be at high load and going off throttle. If so, check the recirculation valve...

.... any ideas ?!?

well, it shouldn't.. it should know its roots better

WANTED fuel pressure regulator for a B18FT. Will need shipping to Malta (will not be a problem as it would be a small parcel).

Hello guys.. My car is acting very weird occasionally. It normally runs very well but sometimes it starts stuttering when on low gears and the idle goes really rough. It feels like suddenly it is running really rich. I've found out that switching off the car and removing the battery terminal and lea...

could be the belt tensioner .. try removing it and see if it turns freely as it should

I can not investigate further due to lack of time. I give my volvo to a car repair shop. The EZ210K seems to be fine. They found that the distributor was oily and the contacts are burned. The turbo charger is not damaged. I am not shure about that statement, but I do let them repair the ignition pa...

I've got the same problem. But my 480t engine starts delayed and then running normal in idle speed and sometimes cut off immediately. If I accelerate fast, the engine stumbles. I investigate the EZ210K.

I've already tried replacing both ECU's. Still same problem.

did you replace the fuel-filter? The engine is installed in my Renault 5 so the fuel filter isn't the original size, I had to replace it with a slightly smaller one. I had replaced it just some time ago but maybe as its smaller it needs changing again, or could be its restricting the flow because o...

I've tried unplugging the ICV (Idle Control Valve) but it did not make any difference (obviously apart from a very low and intermittent idle). I've also tried two other ECU's, to rule out the possibility of one of them being faulty. Still same problem. I've replaced all thin vacuum lines with new si...

I hope it can help you.

I'll try that ! Thanks for your help..

Ignition coil, plugs and rotor arm are all new. Only been on the car for 4 months and as I said, I use the car very little.

ohhh and I've tried resetting the ECU's too! at first I thought it could be something to do with overboosting (it shouldn't as I have a richmod) so I've left the battrey disconnected for a whole 2 days (I only use the car occasionally) but problem was still there

Hello there fellas, I've enjoyed my car for some time with no problems but here we go again... When I try to floor it down on a lower gear it accelerates up to 3000rpm and then starts to cut. Seems to be a fuel problem. Car starts up normally and keeps idle very constant at 850 - 900 rpm. It also ru...

You where right man !!! The fault was the MAF sensor !!! I did not check the bloody thing as I never could have imagined that it would have been it ! I bought the unit brand new about a month & a half ago ! :angry: I've sent the company an email, I hope they have good customer service !!! Damn non-o...

I have a spare one, will try it tonight. Thanks for the help mate!
