Leads/Ignition

[comfortablynumb]

the only thing ive tryed so far is injector cleaner but no different.so you suggest to try changing the leads and ignition?

[comfortablynumb]

also some times it backfires from the airbox

Is it on LPG?

If not, do your leads and plugs.

[comfortablynumb]

good starting point is>>>>>>>>> change the coils, leads and plugs

[EDGE3]

It could be a lead,but 9/10 times its the bloody coils

[vicious01]

to save buying a new coil pack test them with an ohm meter, they should all read very similar. clean/gap your plugs and then throw some new leads at it. if it is constantly 1 cylinder down it could be the module block. all easy fixes, just try the cheapest ones first

hey, I've got a VT Supercharged V6 , and every time i put my foot down and rev it up to 60+ it won't go you feel the car jerking up and forth.... they say its the fuel pump... I'm not sure if its the leads and coils.. does anyone know ?

check for codes, if none present.......
start with the basics, plugs, leads, air filter, fuel filter, tps, then work up to the big expensive parts, fuel pump, cas, dfi module, afm

When was the last time your fuel filter was changed?

[Kierab]

had the exact same problem for the last 2 or so months

changed the leads and plugs. nothing

changed the fuel filter. nothing

changed the dfi module and coil packs. worked!!!

so yer go to pickies or any wreckers and bring a set of real small sockets, spanners and ring spanners aswell, all you have to do is unbolt each coil (6 bolts in total) and then the dfi module comes off aswell (try and get one with no corrosion)

smack it on your commy and itll be sweet as.

probably not that order if you want to save money, but having things replaced never hurts i guess

plugs > leads > coil pack > dfi module

dfi module and coil pack is like 30 bux

i had the same problem, even when cruising it would fluxuate between 1.5-2k rpm
didnt have any codes for a while, there were some logged in my history for "tps" and eventually that code came back
its essentially a part that tells the throttle what your doing and if it starts to die you will get a choppy acceleration. if it goes all together you could find yourself stuck in a gear.
