my 306 has compreession
leads are sending spark
sparks coming out of sparrks
changed coil pack no change
took exhaust off no change
air flow tested rising on revs perfectly
fuels coming out of rail
air intake taken off no change
2 and 3 still misfing
mostly at idle and upon revs it wants to die instantly as i start the car ...have to gas on to keep it going ,,, but still steady misfire upon reevs few backfires hear and thier
dies removing 1 and 4 leads when running ,,, have swapped sparks aorund in past pretty sure made no differnce ,,, will check again ,, which brought me back to leads or coil ,,, yet they are all working ?
fuel to much when in block ? is what i originally thought right from the begining or to less fuel say for example ,,, yet all 4 on rail were squirting around the same pressure by eye when checked
i will re check this properly
done almost every test with my mate we are both stumpt slightly its feels liek we going round and round ???
with this misfire
i know a bit about cars im not professional but something doesn't seem right to me like i feel we have checked eveyrhting ive read almost everything possible about misfries and how engines work seriously
my mind says it should be running,,,, maybe im missing something ?
something stupid and prob what ive already checked uno... like my mate helped him with his mirage
same misfire
o2 light on dash
he changed sparks solved problem for a little bit he rekons then back to sq 1
so i said goo buy some leads
got their.... one cylinder of his new spark plug still looked new others were burnt had obviously Fired fine ... so i changed the one cyl lead minor change ,,, weirdly ,, changed all 4 leads drove like brand new again
leads did have orange build up on them
I'm thinking maybe ironically i need to just replaced leads sparks and coil at same time and see if it stops as it seems somethings making me go round and f***n round wit this car ... ahhahaha they alll look fine no white residue on sparks leads coil look new
as I've only changed coil pack because the leads were sparking and the sparks are getting spark . fuel is coming out of rail and air is fine matching revs and compression is good ..... any ideas cheers
i guess people will say just change them all but why when they are working fine i know people will say but under load they may not be as in once they are in the block they cant handle the pressure ?? its all crossed my mind but their must be something i am missing here ?
why change something if its working ?
so then it brings me back to over fuel upon spark ,,,, but then rails squiting jujst fine and air flow is fine ?? ahhahaha anyway thanks in advance let me know where im gfoing wrong !! only way to learn :)
