I'm going to check the fuel pressure, but can't find any images of where the pressure test port is.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

6 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

Got an issue with my C4S. Bare acceleratorates at 3000 to 5000rpm and only gets to 5200 rpm. Really bogs down. Cleaned MAF, also unplugged MAF. Runs great at first but after 5mins when warmed up the issue comes back. I'm going to check the fuel pressure, but can't find any images of where the pressure test port is. Is it this in the picture? Cheers

POST 2Original post

Can you check to see the throttle body is working as it should? Yours is E gas so it's electrically operated. Have you got a scanner?

POST 3 / ORIGINAL POSTEROriginal post

It's fine. Only 9 months old. Obd reader shows is opening 100%

POST 4Original post

I'd get a proper tool plugged in and check fuel trims. You mention a reader so assuming no fault codes at all?

POST 6Original post

The fuel on my 3.4 comes in from the left under the coolant tank think yours is the same so ,that is more likely air con or something else.

This is a source reference. Confirm exact model applicability in the original material.
