Still Missfiring

[dodsworth_gti 11]

and getting worse by the week

 

oh and a search is not turningg up many answers for me

 

changed so far

 

plugs and leads

fuel filter ( in part of a full service)

tried a different ignition amp.made no difference

dizzy cap and rotor arm

checked all electrical joints and plugs,cleaaned and gave them some wd40

 

 

now its getting worse and its now struggleing to idle or on the other hand it idles really high

 

rev gauge jumps about like its swallowed a pack of pro plus and its getting embarassingly slow!!!!!!

 

any help would be great

Assuming its the mi16 in your signature.

 

could be blue ecu temp sensor (on thermostat housing)

AFM

get a compression test and post the results. if its under 180psi its a bit low.

[dodsworth_gti 11]

ah yeah should have said,its a 1.9 8v mate

 

compresion test is what im next waiting for

The ecu plug in below the sad then.

with the tacho jumping around, sounds like ignition related, I'd suspect the LT lead from the dizzy. Can you borrow a known good dizzy? Apart from that it seems only the coil is left to replace? worth a try.

[dodsworth_gti 11]

dcc - ill check that this aft

 

lt lead??? is that the one that goes to the coil??? as thats the only one i havnt changed

 

dont think i can get my hands on any dizzy's at the moment

 

might try get a coil this aft

I had similar issues with my 8v when the headgasket went come to think of it, go get a hydrocarbon test.

Low tension lead - from dizzy body to ign. amp - but if youv'e not replaced the king lead from dizzy cap to coil - that's your 1st priority!!!
