Running problems

[m14caa]

Hey guys need a bit of help,
had a running problem for a while now, keeps dropping cylinders,
things I have changed

plugs
leads
dizzy cap
rotor arm
coil
igniter

has been running fine since I changed the last 2 but hit a majour ass pot hole today and it dropped again

would like to no if anyone has any other ideas cos I'm all out, at the moment only seems to be running on 1 and 3 cos when I pop a lead off it runs until I pop off one that it's running on

really starting to get me down now and this has been a problem for months now

hope u can help me out

thanks

So basically ure only running on 1 and 3 and its intermitant ?

u sure as it was running well before u hit pot hole, that u havent moved/ dis-lodged an ignition component mate.

It was fine before hit the pot hole then it went

ye running on 1 and 3 at the mo, checked the dizzy cap and it's contacting on all 4

I agree with jayc .its obviously an ignition part or sumin electrical bin knocked. U need to check it all over carefully. I dont know wether its worth doin diagnostic?

 

[starletgtturbo1]

check you earths mate? and do a diagnostic

are you getting spark on ht leads 2 and 4 at the plugs??

EDITED;

 

[jayc-glanza17]

may have dis-lodged earth matey as u got hue rims and coilies.lol
check to see if u get any sparks mate on 2 and 4.

Got various earthing points and diagnostics is coming out clear but I will have a check over thanks guys

 

[corofin12345]

check the ht leads mate at 2 and 4 at the plugs.. if no spark there its ur dizzy

you may want to check the injector/ sensor earthing block, which basically is a bunch of 4 brown wires, stuck onto the same bolt as the idle valve.. have a look there mate, if u find a loose connection then, there lies ur problem.

Exactly what kon said! I had one of the injector earths slighty loose & my car would be fine & suddenly run on 3 cylinders
