Problems with Opel Omega 2002 - smoke, engine warning light, cold start, jerky acceleration and fuel consumption

Black smoke from exhaust on acceleration

|

Longer cold start time

|

Strong exhaust smell

|

Poor fuel economy

|

Jerking on acceleration

|

Loss of engine power

|

Check engine light on

Hi folks, my 2002 Opel Omega with a gasoline engine is currently acting up. When accelerating it smokes black from my exhaust, the engine warning light is on, the cold start takes longer than usual and acceleration feels jerky. In addition, there is a loss of engine power, high fuel consumption and a strong exhaust smell. My first thought was that the fuel pressure sensor could be faulty. Have any of you ever had a similar problem and can give some troubleshooting tips? Please tell us how your garage solved the problem and what your experiences were. Many thanks in advance!

Hey, I had a similar problem with my 2000 Opel Vectra, I have minimal experience with cars. I took my car to the garage and they found out that my cable connections were faulty. It cost me 155.0 euros but after that it ran like clockwork again! Could you give a few more details about your car, such as mileage and when you last had an inspection? After all, every model and year has its own peculiarities and maybe that will help.

Hi, my Omega has already covered 174171 km, the last service was recently. I really hope it's something simple... I'm not in the mood for major repairs. I'll take your advice to heart and have the wiring checked. Many thanks for your help!

Hey, no problem, always happy to help! With the mileage, it's quite possible that some parts just give up the ghost, despite regular maintenance. Your symptoms remind me a bit of a problem I had with my Vectra. The cable to the fuel pressure sensor was broken and had strange effects when accelerating. Maybe it's something similar in your case. In any case, have it checked at the garage. If that's it, the repair can even be quite cheap - in my case it was around 130 euros. Good luck, hopefully it's nothing serious!

Hello, thanks again for the valuable information! Yes, I will have it checked at the garage. Hopefully it really is just a cable problem with the fuel pressure sensor... and nothing too expensive. I'll keep my fingers crossed! Thanks for the get well wishes, I'll keep you posted!

My Opel Omega B2 110kw smokes black when accelerating after changing the 6 injectors.

Black smoke from the exhaust after changing injectors could indicate that the new injectors are delivering too much fuel, causing an overly rich fuel mixture. This could be due to incorrect injector calibration or a problem with the engine control unit (ECU) not adjusting to the new injectors. I recommend having the injectors and ECU checked by a professional. Please keep us updated on your progress. Do you have any other questions or concerns?

Is it possible to program the injectors? Because they are originally for a 3L engine and my car is a 2L5.

Hello Amzil, As you have used the injectors which are not specified for your vehicle type, this might cause the black smoke. I always recommend you to use only Opel authorized parts specific for your model to avoid these kind of issues. Please keep us updated on your progress. Do you have any other questions or concerns? Best regards, CarlyAdminNik.
