Hello all! I'm at my wits end and am hoping that someone out here might be able to help.

I am working with an 08 Clubman with 72,000 miles. The car starts and idles fine, but when you give it gas is just falls on its face almost like it is starved for fuel or air. Here is what has been replaced since trying to diagnose: 1 VANOS sensor, air flow meter, fuel filter, valve cover with pcv valve, spark plugs. Gas has been emptied and filled with new fresh gas.

I'm getting a P0301 and C0700. I tried swapping coil number one to a different cylinder to see if it would change the P0301 to another cylinder, indicating that the coil is bad, but no luck. Also, not too long before we had this problem we had a full timing chain service done. If you could help shed any light on this I'd appreciate it.

Could this be a symptom of a High Pressure Fuel Pump? Or maybe the pump in the tank?

 

Not to doubt what the mechanics did for the timing, but do yourself a favor and take off the valve cover and take a look.

Is this an S model by the way?

 

It is a base model.

You can rule out the high pressure fuel pump. A base model doesn't have one. I'd still check pressure at the rail to verify the in tank pump is working correctly.

 

Yep no HPFP, check the rail and then make sure the fuel pump is working and you can hear it making the whirl noise in the tank.

 

Update. I have replaced the exhaust VANOS sensor and the Fuel Pump. Still having same issue. If I floor the car it surges from 2500 to 2000 rpm up and down. Will not go past that. Pedal sensor in my reader says it is at 100% when fully depressed. Could a throttle position sensor cause this?

 

when the car is in limp mode, it will not allow the driver to rev it that high. same when you have a misfire or some major issue.

Since you can read live data, you can read the throttle position. also, it is a good idea to start with a compression check.

 

I just replaced the timing chain on mine, and it ran like crap, until about 700 miles and then it just leveled off all on it's own. So I'm very much interested with this. And make sure you check the bolt in the crankshaft, if it's not set it can make it jump time.
