Had experienced something strange yesterday. I wanted to start the engine but it went off all the time. After about 7 he ran. I then went playing tennis with my daughter. After 2 hours I wanted to drive home. Motor started normally and after about 1 km at the intersection noticed that something was wrong. Didn’t want to speed up so properly. I stopped immediately to check if I didn’t forget something when changing the valve cover seal (which I did at the glacier). the day morning changed) Then I just wanted to drive slowly. Engine was very jerking as if driving with 3 or 2 cylinders. Again immediately stopped and backwards to the parking lot. Disembarked all ignition cables pulled on and then wanted to turn around and immediately drive to the acquaintance 3 km further into his workshop very slowly. Gang in and then mega cloud came out of the exhaust (but my was quite horny) to it very loud noises from the engine as if what had broken off or a loose chain ) I took foot from the gas and called home. Engine ran but. Then I wanted to try to continue driving anyway. Go in and very slowly with little gas tried. No more smoke and engine noises also away. So I slowly drove towards the workshop and became faster. After 1 km stopped a little more accelerator pushed through and everything was normal. I then drove 7 km home and car parked in garage. Could be that the ignition coil spinned and m more noble cylinders had failed and unconsumed fuel was burned at once because of this smoke cloud? Who has an idea? Captiva 2.4 LPG 2007 136 hp
