I recently went back to no DV and custom inlet pipework as I was not happy with the Perrin setup.

When I fired engine up after swapping inlet all seemed ok but after a few minutes on tickover it started to splutter, engine was really unstable as regards "wobbling" from side to side like mad!!!! never seen that before

I plugged in OBD machine and was given PO301 and PO303 misfire codes for cylinder 1&3 respectively.
Under tickover you can hear the fuel pump periodically trying to supply fuel and it sounds crazy.
Last thing, tried to drive the car and there is NO drive above 1500rpm.
You could smell a fuel vapour in the engine bay but that has gone now, I know I may have done something but don't know where to start.

Please help if you can

Cheers

 

have you had the inlet manifold off?? maybe the gasket isn't sitting correctly, or you have missed a vac pipe somewhere??

also check to make sure you have not disconnected any wiring plugs by mistake.

 

I'm off to check now just got in from work, Cheers lads

 

SORTED!

When I put jubliee clamp on end of 90 hose I mamaged to feed it around the fuel line, just the bit where it goes from solid pipe to rubber then back to solid under the inlet manifold. I split the fuel pipe by virtue of tightening up the clamp.

Cheers for your help
