England Flat engine ?

Ive had my R50 cooper for a wile now but have never really been happy with the lowdown performance. The engine just feels flat at low revs it revs ok no misfire. Ive driven a few others and they don't feel like this. It happens no mater what the engine temp. Ive tried new plugs, filters ( inc fuel ) . Ive cleaned the contacts on the coil pack, the only thing I can see is that a couple of the plug leads have a little corrosion in them , but not any on the contact surface. Done a compression test , 3 at 180psi and 1 at 190 on a cold engine .Also you have to be careful how you pull away as the throttle seems very sensitive you can easily stall it. Anyone any idears before I splash the cash on a new coil pack?

Hi ya

You could look at the following

Get your fuel pressure checked you may have a weak fuel pump.
fuel pressure regulator checked plus it's internal filter screen.
Vacuum lines to fuel pressure regulator.
Get you emissions checked you might find you have a bad O2 sensor which is messing up the fuelling.
Map sensor.

You could try putting a can of bg44k fuels system cleaner Incase you have some bad injectors

Also try doing a ecu reset Incase it has got some bad habits

Hope this helps

Thanks for the idears Marque. Had a quick look today and found that the vac pipe had been almost chafed through, done a quick bodge till I can get a new one. How do you get to the fpr filter? I pulled the clip off the fpr and I take it the filter is underneath and just pulls out . Its very tight so left it alone for now. When I changed the tank filter it was almost clogged so some crap could have got further down the system. As for the pump pressure will have to get that checked out, but as it goes ok at the top end I would guess that's going to be ok..........??

Hi ya

Good news on the pipe :-)

I found it best to remove the injector rail turn it upside down
Remove the fuel pressure regulator clip, then give the regulator a good wiggle and pull at the same time. As it comes out on the top you will see a small filter screen it can be carefully removed and cleaned. While the filter is off you can fit item 10 easer
Make shore you replace the orings and clean up any fuel that might get spilt.
My one had a little bit of crud in it nothing to write home about but it should not be there

You will need items 5, 9 and 10
