01 2.0 management light - inanimate

dear honest john the engine management light keeps coming on intermittently and sometimes when it does the engine will only idle and will not rev after 30 seconds or so
the engine will pick up and the car will run perfectly for maybe 50 miles even though the engine management light stays on any suggestions as to the problem will be gratefully received
many thanks inanimate

Light on = fault = car goes into 'limp home' mode.

In short you need to get the fault code(s) read out to establish what has put it on.

01 2.0 management light - The Gingerous One

Possibly nothing related to your problem but my mate had something similar, also accompanied by a misfire.
Codes were read, and, helpfully said "misfire on cylinder 2"

We took the engine top cover off and detached all the HT leads and cleaned out all the oil that had ended up in the plug holes (mate has a 156 2.0 twin spark, so 2 spark plugs/cylinder).
Thing drinks oil, my mate just gobs a load in every so often and often it all spills over and just under the top cover and straight into the plug holes for cyls 1 & 2.
One HT lead broke during cleaning so we bodged it with cable ties (you can't see the bodge due to the engine top cover :-) ) and things were a lot better afterwards.

He ended up getting a second-hand set of HT leads & coil packs off e-bay once some further diagnosis showed that the coil pack or lead on cyl 2 was failing. he now has 3 spare for when all the others go.

so don't overlook the simple.

cheers

Stu
