Hello, Bonjour, I have a problem with my Renault 21, 2,0 GTX Injection, 1987/265.000 km. By the speed of 100/110 km/h and engine speed 2800 rpm the engine jerks very badly. This happens with cold and warm engine in winter and in summer. Trying to fix this I lready changed the spark plugs ( Brisk Premium ), the ignition HT lead connections, the rotor arm, the distribution cap, the fuel filter and the air filter. The fuel pump and the generator are also quite new. I tried fuels with different octane ratings as well, and I put some Injection Cleaner and an Gasoline anti-icer to remove water from the fuel. Both the Ignition and the exhaust analysis was checked by the Renault service and its OK. If You have any idea about the reason of this jerking, or You know what else I should check once more, please let me know! You can write me in english, german, finnish and polish.. Thanx !
