seems a bit irregular when driving steady with the odd hiccup hear and there

also seems to cut out a bit when starting sometimes as if ive not held the starter in long enough

but then i have to floor the throttle to get it to go - and hold the revs above 2k for a bout 10-15secs before it will idle as normal on its own?

any ideas whats the first port of call to check?

Leads, these are a problem on zetecs they can cause the car to run terribly

by **M Brian** on Thu Jul 17, 2003 1:26 pm

oh no!! LOL

theyre only about 9 month old - ill have a look at the routing see if somethings moved or sumut

My last set didnt last me very long at all either,
Not sure if your using the standard ford ones are not, these are ment to be the best, but they can still go really quickly. Something in them goes and they start to short out, usually on the plug end, but sometimes both ends

by **M Brian** on Thu Jul 17, 2003 1:31 pm

is there anyway of testing them?

by **Rich si** on Thu Jul 17, 2003 1:37 pm

not that im aware of, the end of oone of mine looked cooked compared to the others, if that helps!

Other than that try a set from another 16v thats running ok.

suffer from high resistance from lead to plug>solution put smear of silicon grease inside the leads and pull em on and off the plugs a few times, can use normal grease aswell....

Cheers geoff!

Will remember that when i change mine.

snake, tried the grease lasted a couple days r my h t leads cooked.

:-?

by **snake** on Sat Jul 26, 2003 11:10 pm

grease cured it then for a few days?, if so yeah points to leads problem, amount of abuse they get they should be replaced now and again anyway, zetecs normally last 5 years or so, but go off after a few years, think about it u got in excess of 40000 volts goin through em, they do take a hammerin :wink:

, if ur plugs have done more than 30k or more than couple of years old, get a new set of ford or ngk items in their

cheeRS snake its been a nightmare.

by **snake** on Sat Jul 26, 2003 11:15 pm

nitemare? common fault, 30mph 5th gear, full load, if it misfires ignition fault and chances are on a zetec its plugs or lead, if not then coil pack..

by **LEE.16v** on Sat Jul 26, 2003 11:19 pm

thanks m8, gunna replace leads +plugs tommorow.

by **M Brian** on Mon Jul 28, 2003 8:27 am

how long do the plugs last? mine does the hiccuping under full load at 30mph in 5th now - and at a few other points in the range

also when starting the car

ive done about 11,000 miles on my NGKs

Great tip Geoff!

Sounds suspiciously like the problem I'm having.

I have a sneaking suspicion mine is TPS-related or possibly MAP (yours could be lambda probe, MAF or TPS) as mine jerks hard between throttle closed and very slightly open (and vice-versa as well).

If your fuelling's spot on, try a different TPS

Also might be worth checking how clean the inside of your MAF is too.

by **M Brian** on Mon Jul 28, 2003 2:19 pm

MAF is pretty clean did that the other day

i always suspect the TPS! lol -- its the 2nd one ive had on but 2nd hand as I havent got £65 to spends on a maybe

not sure on the lambda but that sounds reasonable as the problem gets worse the hotter the car gets

Same as mine - I know mine's running lean but by how much, I don't know just yet.

Mine might behave itself better with a higher rising rate fuel pressure reg (e.g. FSE Boostvalve).

pull leads off and on a few times and smear with silicon grease if u got it if not normal grease or wd40 if u aint got nothin else, lol

by **M Brian** on Tue Jul 29, 2003 12:37 am

ill have to give that a crak tomo

normal grease as in copper slip? if nto ill have to resort to WD40
