missfire 2.0 8v

[tashley6]

I have a serious miss fire but Its no just 1 its all 4 cilinders that cut on and off changed coil egr valve and also tryed bypassing the fule pump still the same any ideas?

[dougie_boi]

injectors due to dirty fuel. could be plugs leads cap or rotory arm as well

[tashley6]

Will change injectors went through leads arm ect thatks any other ideas ?

[dougie_boi]

check the earths one from the battery to the body and one from the gearbox to the chassis leg

plugs leads cap or rotor arm first, mine had terrible running troubles when water got in the dizzy, worth taking it apart cleaning it and spraying some dw-40 in, then take it from there. When did it come on? all of a sudden?

[tashley6]

Yes was all ov a sudden and iv already done the dizzy cap cleaned it we'll it was spotless any how it seems so weared cus the only thing I have done is took the old aftermarket rev guage out aud re wired it to some gsi clocks problems since then but put old clocks back in to try solve and still smae problem!!

Don't know then, could be a bad earth but not that likely unless you've disturbed any of them. The plugs ok? what colour are they? maybe worth checking the plug gaps but again unlikely unless you've touched them recently.

You could check the earths off the injector rail that goes to the block, mine ran badly and was ok after cleaning both of them. Just check everything really to rule stuff out.

Think that's the best idea really was on with it last nite till 10 haha. Got to be sumthing behind dash that's what I was messing with just befor the miss fire thanks any how if any1 thinks of anything tho

Agree. Thats the 1st step.
Secondly I would renew the rotor arm unless its like new, check the dizzy cap condition & the plug gaps. (0.6mm)

[tashley6]

I think you might av just make me click!!! Will the engine runn with no earth from the engine to the body?

[dougie_boi]

sometimes lol can just depend on the condition of the earths quick way to check if its an earth is get a jump lead and stick one end on engine and other end on the body but make sure it gets a good connection either end and see if that makes a diffrence. as the engine needs a sepparate earth due to being on rubber mounts it needs its own earth to the body.

[tashley6]

Sying that the battery lead goes straight to the block on the car!!!

[dougie_boi]

if the earth from the battery goes straight to the engine block you will still need one going to the body of the car

[tashley6]

Problem solved!!!! The earths are fine 1 to block 1 to body off car it was. The air flow meter crap connection due to k&n bracket burnt out the fillement when pluged bk on propley. Runs ok but gose in to limp mode every now and then and also misses every now and then on ticover thanks pal

That was next on list but worked my way through everything from simples like leads to sensors but problem found these thing are sent to try

[Riggy]

the missfire is prob down to all the damage that you have done with the engine running without fuel and melting your pistons etc etc

[tashley6]

No damage don pal runs sweet as a nut and compression is well high enough dropped verry little from new
