Citroën C8 petrol engine 2005: Symptoms of power loss and uneven engine running

CITROEN

| 2005 | | Gasoline

Car won't start

Loss of engine power

Shaking while idling

Jerking on acceleration

Unsteady engine

Longer cold start time

Check engine light on

Black smoke from exhaust on acceleration

Stalling while idling

Hey guys, I need your opinions. I have a Citroën C8 petrol engine, built in 2005 with around 47,121 km on the clock. During my last visit to the mechanic there was some trouble and now, lo and behold, something is wrong with my car. When accelerating, black smoke comes out of the exhaust, the check engine light is on, it takes longer to start when cold and there is a loss of power. In addition, the engine doesn't run smoothly, jerks when I accelerate, sometimes just won't start and has even stuttered when idling. So basically pretty much everything that shouldn't be. I suspect it could be something with the mixture preparation. Has anyone ever had similar problems and can share their experiences with the garage? Would really appreciate some tips! Thank you.

Hey buddy, you were on point. The last time I had my 2008 C-Class Benz in the shop, I also had problems with the fuel pressure regulator. Really sounds like your car has a similar ailment to mine back then. Black smoke and problems accelerating, had them all. In the end, the fuel pressure regulator on my car had to be replaced. It was a bit of a pain, but once it was replaced, it ran like a champ again, no more smoke, no jerking and plenty of power. So, that could definitely be your problem. So, long story short, definitely check out the fuel pressure regulator. Speaking from experience, sounds like that's exactly your problem.

Hey, thanks for the quick reply! Your experience sounds exactly like my current drama with my C8. So the fuel pressure regulator, eh? Can you remember how much all that fun in the workshop cost you? And were there any other problems afterwards or was everything fine?

Moin Moin, you're welcome, I'll help where I can. Yes, I won't forget that fuel pressure regulator hassle in a hurry. The bill for changing this part cost me €250 at the time. A decent chunk of money, but since then these particular problems have been history. Apart from that, my bike ran like clockwork after the workshop visit. Above all, these mixture preparation problems were eliminated afterwards. So, off to your mechanic and have your fuel pressure regulator checked. Keep your fingers crossed that it's exactly that and your car will run just as well as mine. Good luck, buddy!

Greetings! Many thanks for your help and your experience. Of course, €250 is a bit harsh, but if it fixes the problem, then it's worth it. I'm just fed up with this constant hassle. I'll follow your advice and call the garage tomorrow to make an appointment. Thanks again for your help and keep your fingers crossed for me. See you next time. Bye!
