Hello, drive for about a week a 90s Senator B 3.0i with 177ps and so far is the car top, but I noticed that he especially when you start driving in the morning not sooo well take gas and slightly jerk, over 2500 turns it is not so noticeable or if you give a lot of gas, but when it is cold I switch at 2000. The previous owner said that the spark plugs have probably not been changed for longer. If the car is warm, then it is only if you are not ertourig(approx.1500-2200 turns) drives minimal!!! Performance he has in my opinion full Is just when he is cold quite annoying, because he takes the gas quite badly… What would you say, what the problem can be?? Air hoses are all tight, I have already looked!!!!! Would I be very happy about help Dear greetings Christian
