My Omega A 2.6 from 92′ has installed a cold running controller from Euro 1 to Euro 2. It was already installed at the purchase and is, to my knowledge, an electronic one from HJS. The problem is, if I start the engine it runs higher because of the KLR, about 1600 revolutions. If I then drive it warm a few kilometers the idle speed is constant at 1000 revolutions. Only when I switch off the engine, and a second time was m start the engine has its normal 600-700 revolutions in the stand. The second phenomenon is that the KLR regulates even when the engine is warm, i.e. I drive and suddenly the engine gets gas shocks, without which I give more gas. Just at the gas station everything was good and all of a sudden it gives itself gas in the stand people have already looked at me. My question is what is broken and if you can just pull off the plug of the KLR on the controller to see if this is the cause of the error. l it’s an electronic one that’s stuck between the vacuum hoses or not? Maybe one of them had a similar phenomenon. So it’s not possible if the engine decides to give itself gas at once.
