hi all my car has started to hesitate underpart and full throttle application i have got a video of the peddle test if someone can decode it for me or if anyone has any ideas what may be causing it ?http://s1173.beta.photobucket.com/user/Russ_Hill/media/2CCD5585-D409-4EB1-A56A-4C0762FD4FC6-7029-000005EDDE27769E_zps1909f2ab.mp4.html (http://s1173.beta.photobucket.com/user/Russ_Hill/media/2CCD5585-D409-4EB1-A56A-4C0762FD4FC6-7029-000005EDDE27769E_zps1909f2ab.mp4.html)

Not very clear, but at least one misfire code :-\
Pop the coil packs out, and go from there, will be either oil or water in the plug wells.
If oil, then camcover gaskets and breathers, if water, the scuttle needs sealing up, as per the guide. It also helps if you remove the sponge from the scuttle, as that drip feeds the 246 coilpack :'(

:( :( :( :( :( thanks not good then

Had a quick look today can't see or smell any obvious oil leaks around the rocker covers and the foam on the scuttle is bone dry . When I had the rocker cover gaskets go on my old 3.0 it was leaking onto the manifold do they tend to go round the plug wells first on the 3.2 . The fuel filter is looking rather old is there a possibility of fuel starvation causing the miss fire and hesitation ?

Would have thought that the fuel filter would show as an injector fault rather than a misfire :-\
Lifting the coilpacks for a looksee is alot easier than changing the filter :y essential to rule them out tbh, can check/change the plugs at the same time :y
Did the 2.6 loom stay on the car, or was the engine fitted with its original loom :-\
-
I don't know as I didn't do the conversion robsymv6 did it . I know it is a silly question but does the plenum have to come off to pull the coil packs ?
-
There's a knack to it drivers side easy enough, pass side, remove filler neck, aircon pipe bracket, undi vac line and cable tray. Push cable tray towards wing and should have enough wiggle room :y

right pulled the coil packs today and they are dry as a bone so none the wiser . i did take the breather box and the throttle body off and cleaned them the breather box was full of a nasty brown gunk mostly in the outer large bores i cleaned them through with carb cleaner and a hose pipe but the carb cleaner made the o rings go brittle i managed to find one that fitted the bit that goes into the plenum but it doesnt have the bit that wraps under the bottom of it . run the car and couldn't find any air leaks using a spray to see if the idle changed . so i am still none the wiser please help ?

Here's a tip, once you have access.

thanks chris i done that to get them out plus plenty of swearing and the wells were dry
-
If Rob used the 3.2 plod loom, the coilpack wiring might be past its best :-\
-
ahh thats not good news al i will have to pm him
:'(
-
oh and regards what al said about the filter i agree what a stupid place to put it its a peace of cake on a saloon to change with nothing but bare hands i still cant get the one off my estate so i am going to have to buy a filter clip tool
-
9 months ago the loom could be bought new for about £120, now they're over £500 :o. Wish I'd bought one then ::)
-
Fwiw, mine is currently running an auto engine loom :y
You need to rewire the plug for the reverse switch, as auto very different, so a couple of extra plugs for the gearbox, but rest is plug and play :y
Any loom from any 2.6 or 3.2 will be fine :y plod ones seem to go brittle, probably as a result of heatsoak from being caned ::) coilpack loom gets the worst of it as the wires are relatively light and the plugs for the coil packs sit above the manifold/downpipe join :-\
-
Used all plod loom so you have the manual loom Russ.
-
ahh thanks rob i will have to have another search for the cruise wires again or is the loom under the dash still the auto loom ?
had a mate put his snap on code reader on the car today only faults that came up were clutch switch fault ( well that will be because its not plugged in ) both cats low efficiency . and 0001 maf something or other didnt get chance to copy it down fully before he cleared the faults :-\ no mis fires were recorded ?
