Missing Through Entire Range?

[jared87]

Hi my T has now started missing thrrough the entire rev range very faintly but very noticeable when you hold the throttle perfectly still in the one spot. Ive had nizpro springs fitted, 6 new coils and numerous sets of spark plugs and nothing has made a difference. What Now??????????? Oh and by the way my mechanic has a carman scan tool and it did not pick up any faults at all, but he thinks there may be a better diagnostic tool than his as he is a Expensive Daewoo man.

Were any mods done before it started missing? or did you replace the valve springs as a possible solution to the miss?

Yeah I did but it was only a little pop on idle but now its everywhere, its been about a month since the springs were fitted though.

I'm no expert, but do you think it could be fuel related.

Try changing the fuel filter

ive changed three fuel filters in the last three months, unless it has clogged an injector but that's what I thought the filter was for.

spark plugs gapped correctly??

I don't know then mate, was just trying to help.

Maybe take it to a site sponsor to get checked out

Yeah ok thanks anyway

Can your mechanic check your fuel pressure? What about the signal for the crank sensor? Can you get scantool on it and run it up on a dyno to check these issues out?
