Mt beast has been running like a 2 stroke diesel tractor recently when warm and being very reluctant to accelerate and jerking.

 

Very embarassing when you get into a race with a Almera on a motorway from 50mph in fifth and you lose!

 

I've done the usual (checked tps, cleaned throttle bodies and temp shitch) but short of changing the plugs I am lost as to what is the cause. Oh yeah it's only on the right hand bank as you're sitting in the car as well.

 

Ivan (very frustrated with lawnmowers!)

check the coilpack connectors. They have a tendancy to come apart on there own as most of them will be broken.

Only happens when warm?

 

Sounds like not firing on all cylinders.

 

Sounds like the old PTU to me.

Checked the coil packs - thought it was that at first.

It had a new PTU in September - could it really be gone so soon? I was under the impression that if the PTU went west it wouldn't start at all?

 

Ivan:confused:

Ivan,

 

Check your injector connectors - they go a very nasty green as the years go by. Usually the problem is made worse when hunting for the problem in the first place, since moving a connector will usually cause more resistance between the mating surfaces.

 

A small flat needle file, a can of contact cleaner and a spare hour or so, should see you to a happier engine..

 

Hope this helps..

Where are the injector connectors in relation to the coil pack connectors. I did think that this might be the case.

Take a look about 2 inches lower than the coil pack connectors, and an inch further towards the centre of the engine - you should see a smaller connector (compared to the coil pack connector), with a rubber boot over the top to insulate the wire.

 

Be careful, when removing them, you'll probably require a couple of small flat screwdrivers to prise the retainer clip off without breaking the aged and brittle plastic of the connector.

 

Still if you do break em and/or you want new ones anyway - Courtesy Parts in the states sell replacement ones (in packs of three I seem to remember)

Thanks Simon I'll try this tonite and let u know how I get on.

Well done to Simon you win! It was indeed the connectors. Took them off and sprayed a rust penetrant in them and scraped them with a screwdriver and it's cured!!!!!:D :D :D :D :D :D

 

Ivan

I love happy endings! Nice one mate :D

Good work Ivan, hope you've got back some of your vaa vaa vooom! Might be worth resetting your ECU, if it's been running a bit dodgy for a while.
