Stuttering is still there.

[allstaruk]

Cracked it, my dad who is condiderably better with electrics had a look and said it was an earth fault so after some carefull tracing it turned out to be the earth connection that goes to the block on the cable between the battery and starter motor,

Thanks Guys

do you have any pictures etc or could you perhaps describe where this is as i have the same problems

[m4drx]

please....

[allstaruk]

No worries mate,

First off what are you symoptoms exactly and what have you checked or changed recently?

A

[m4drx]

checked every single pipe on the turbo system replacing as i went along. replaced all check valves and checked all circlips and rods.

replaced spark plugs.
replaced the turbo precontrol and wastegate control solonoids on the plenum twice.

compression is 7.8s all round.

no leaks at all or smoke etc.

have redone all earths to an extent and have put on a voltage stabiliser.

changed all couplers for silicon ones, changed intercoler pipes and crossover pipe.

disabled dual throttle

changed ecu to another stock one.

[m4drx]

and more but i will add as i remember.

my current symptoms are slight hesitation (both tubbys work now) as boosting gradually worsens after a few runs then will not boost over 0.5 bar.

if i leave the car for a bit and come back the same again

[robedwards99]

Try the air temp sensor.

May be completely useless but for a £27 part its wortha try... cured my boost issues.

[m4drx]

i have thought of that but i think my one is working due to the the way the syptoms have stayed (cant remember why atm but apparently it works) im thinking that its injector related atm?

[allstaruk]

Have you checked out the wastegate actuator and wastegate?

Also have you checked the main earth is securly bolted to the block this was the main problem with mine It would check out ok on the driveway but while driving it would vibrate and cuase stuttering.

just need to go outill be back soon

i have done alot of advice posts but more recently i have just searched for everything similar, i would just love to know finally what is the cause of this final (i hope) issue

[m4drx]

i havent checked the wastegate as it is hidden away and i havent taken off the heat shielding etc also since i have bought it i have had a bad earth on it whereby everytime i put something electrical on it would dim slightly or if i put the brake pedal down then it would dim alot.

since then i have sanded and refixed every earth on my aftermarket earthing kit consisting of 6 or 7 points but when i looked at the main engine earth ( the only standard one left i can see that goes into the loom) it was badly oxidised.

i cut some off then some more from near the battery and down by the inner wing spark plug area but although the internal copper was goldish there was some oxidisation all the way down it?

but as i couldnt cut this out of the loom etc if put some gold terminals on and left it? could this cause an issue?

i have a voltage stabiliser and earthing kit but none of which runs into the loom like this one?

anyone a sparky who can help.....

[m4drx]

i have the car booked in to be looked at but i just dont want to make a 5-6 hour journey and it to turn out to be somthing very simple

that way i can spend the money elsewhere
