20v st 4000rpm 'ignition cut' (or something) now not firing on no.1 cyl
yo, thanks in advance.
About a month ago my stock 20v started being a bitch (every now n then).. pulls hard (normal amount of pull for a st) to 4000 then just cuts out like ignition is cut or something (is what it feels like). It also wont let me rev it until its returned to idle rpm after said ign cut, then will rev fine to 4000, Load doesn't seem to mater as it will do it in free rev.
On Sunday I was driving it parked to go to the shops, came back to the car and it wouldn't start.. after a minute of trying it did start but was only running on a few cylinders 2 or 3 not sure. I turned it off had a look, couldn't see anything obvious. when i closed the bonnet and started it, it ran sweet except the 4000 issue changed to random rpm issue.
The strange part is it goes away and comes back, previous to Sunday the 4000rpm issue would come n go, one day/time i could rev it to red line, another time she'd cut out at 4000. After the Sunday experience, i was dickin around with it for about 2 hours with it only running on 3 cylinders then she randomly started running sweet, i drove it down the street n back sweet but when i hit 4000 it started running like a bitch on 3 cylinders.
Now the car wont fire at all on no.1 cyl. Ive changed the leads n plugs, dizzy cap looks ok to me so does the button. Its only no.1 cyl thats no firing.
I have a feeling it might be a dizzy issue just wanted to get peoples feedback.
cheers,
Mitch
