XE on SBD TB's, Misfiring

[scott.parker]

Right then, went out in the car the other day and it's misfiring, it gets to about 3.500rpm in 3rd, 4000rpm in 4th, 5.500rpm in 5th and then splutters/hesitates slightly, like there is a problem with a sensor, would it possibly be a sensor is loose, so it's vibrating and reading the vibration and then making this transfer into a twitch in the timing/coil spark etc etc?

If so what sensor would likely be, and location etc.

Is it still apparent when warmed up thoroughly?

[Ben]

Have you checked its getting good spark and fuel?

[scott.parker]

Plugs are good,clean,all leads are AOK, Injectors are all OK etc.

As for temperature, it dose it when warm/cold, did it at combe first, reason i think it's sensor is my mate had similar thing on his turbo'd 1600 8v, as the engine was rocking too much etc.

but it's not that as mines on solids, so though maybe some sensor has rattled loose?

Have you tried a different crank sensor?

[scott.parker]

If so what sensor would likely be, and location etc.
Scott

No Rick i have not, without sounding dumb, i simply don't know where they are, as i have looked in the Haynes, and cant find them.

Its bolted in the front of the block by the drivers side mount.

[Rick Draper]

It will be just under the drivers side front engine mount. Check the wiring is not broken etc. Worth trying a different one if you can get hold of one for a quick test. Not sure if mbe (is that what management you are on?) is as picky as some (some dont like plastic crank sensors and only the early metal bosch ones).

[scott.parker]

Yeah it's on MBE, i'll check the sensor then, and see if i can buy another for a qucik test.
Cheers.

I'd say it sounds like a dead coilpack as its doing it at different speeds/loads. if it was the crank sensor I'd have thought it would be cak at a given rpm regardless of the gear etc
