hi peeps,

put my engine back in the cossie after new head gasket and rebuilt head and got a missfire ,checked leads ,dizzy cap is new and new rotor arm.

still missfiring

anyone any ideas ?????

 

Plugs?

 

new plugs mate,
just finished out in garage,if you take 1 lead off at a time when its running on number2 doesnt make a difference at all.

 

had it on mine once may be the wires in the plug on the injector m8

 

or do a comp test

 

When you removed the plug lead on number 2, were you getting spark from the lead to the block? If so, check the fuel injector plugs. In the past I have seen one of the pins in the injectior plug connector retract and not fire the injector.

 

+1

 

think will do comp test and look at wiring loom 2 !!!

cossies, dont you just love em

 

Stick with it Daz, you're almost there!!!

Do you know if you've definately got a spark on No. 2?

 

hi simmo,
yes got a spark on no2, just wont clear,
sounds like anti lag

 

I agree

Check the simple things first

Steve.

 

cheers peeps

 

Have done compression test on all 4 cylinders and that is good
THANK GOD !!!

The misfire is spitting out the exhaust and sounds like anti lag with the popping, it also seems very flat when giving it some revs

Any ideas ???????????

Thanks in advance

 

thats good news daz

 

you haven't mixed up the iscv plug with the injector plug? easy to do if its a 2wd loom as the plug is the same colour iirc 7 number 2 injector is the only the iscv plug will reach

 

sure you timed it up right?

did you use the old CPS? if so these are quite tempremental; give the connectors a clean and a wiggle

what about phase sensor? new or old

i bet its CPS (crank position sensor)

 

sorry ,do you mean idle control valve

 

put new CPS on and still doing it

It seems strange cos you can take lead off plug on number 2 and nothing changes but if you take other 3 leads off it changes noise ,if you no what i mean

 

yes m8, idle speed control valve
