    Chevrolet Tahoe 2007 engine just quit while driving.

    Thank you for your funny answer. Your German is probably better, how many Germans try to speak English. Regarding your comments. I've already cleaned the throttle body. As I said, I know my Tahoe almost by heart. I'll definitely check all the other Groundding points. What could also be the...

    Chevrolet Tahoe 2007 engine just quit while driving.

    Hello forum members. Today I had a strange situation on my way to work. I was driving down a hill as normal when I noticed that my engine had completely died. Of course, I had hardly any braking power, and the steering wheel was difficult to turn. However, all my electrical components were on...

    Proposal for an tune on my Tahoe 5.3 2007 LTZ (Germany) with LPG system

    Hello everyone @Geotrash , @j91z28d1 . Yesterday I wrote to my LPG professional and converter again. He also told me that it would be typical behavior if you wanted to climb mountains with a wall unit attached to the back. Since LPG has a higher octane value, but a poorer energy density than...

    Under load there is a brief loss of power which sounds like cylinder deactivation.

    I found the actual error. It was my air conditioning compressor. He simply reduced the power too much. Apparently he was just too old. I have now installed a new one and lo and behold, you can notice that it switches on, but I no longer have this dramatic loss of performance. I'm glad my Tahoe...

    Dramatic loss of Power with AC on

    I have the same problem on my 2007 Tahoe. I lose a lot of power when my compressor switches on. I have already changed new spark plugs, ignition cables and the ignition coils. As soon as the compressor is switched on it feels like it is running on 4 cylinders. But only when it turns on. Three...

    I want to replace my ignition coil, which one do you recommend Tahoe 5.3 2007

    I have a professional Aircon Sevice device in our workshop. We first vacuumed everything to eliminate a small leak on the service valve of the air conditioning system. The valve seal was no longer so good. After that, 1134g of refrigerant and 336g of oil were filled. According to GM's specifications

    Under load there is a brief loss of power which sounds like cylinder deactivation.

    First of all, thanks for the tips. By chance, I have already found a few posts here in the forum that had the same problem as me. In this case, cleaning of the throttle valve was suggested. Someone wrote that a user had replaced the compressor and it didn't work at first. Only the cleaning of...

    I found the problem. It is the air conditioning compressor. As soon as it turns on, I lose a lot of power. I had never had that before. As soon as the compressor clutch engages, I have a massive loss of performance. That I can hear it as described on the engine noise even really loud. My...

    I used a Prins VSI with Valve Care. I have a great workshop that knows a lot about LPG systems. They had already removed all the injectors and tested the rail on the test bench and they inject perfectly. What initially prompted me to change the spark plugs, ignition coils and cables was that I...
