i cut off the dett wire connector at the top of the engine and soldered the wires together. I then left the batt off over night. Ran the engine for 5min then checked and no errors. Drove the car some more and it came back after a day. The problem is more hesitation than misfire. Doesnt sound like a missfire, just a total power loss and refuses to accelerate. Fine on low boost tho, now i changed my maf. It feels just like it did when the maf was playing up but only happens on high boost. Im going to change the plugs at the weekend just in case and maybe try yet another maf. I use a john dixson chip and greddy boost controller so no safety boost. I asked before if code 34 would cause the ecu to change the a/f mix or ignition timing as it feels like its down to something like this. + it only does it above 3-4k so sounds like your right. Was the same when it was the maf, only above 3-4k rpm. What im really worried about it melting a piston etc if the mixture is wrong and i keep nailing it to test it. Ed

Me too! I am looking at bypassing mine now.

not good when they get wet tho!

we got enough girls for a calendar yet?

i can see this being a popular thread

well at least its not detting then. Im going to change the plugs and reset the ecu again If i get code 34 again ill either put a resister in or take it to mickyb

so would detting feel like a total loss of power? I cant hear it rattling so maybe its not detting. The only thing that bothers me is that I only get code 34 after hard driving. With the ecu reporting this code will it effect my a/f ratio and timing enough to cause the misfire on high boost? (i use a pro spec 2 and john dixon chip/map)

well ill change the plugs and if its still the same its going to mickyb

You never think that it could happen to you or anyone close, it makes you take a step back from it all and think. RIP DAB 1

but is code 34 det sensor fault or dett has been detected?

Also if im getting 34 will it effect my a/f mix and timing? Could this itself be the cause of the misfire? My car has no safty boost unless i turn my controller off for a while. 13psi with the ecu running code 34, could that be the cause if the misfire at high rpm?

changed the maf, ptu etc plugs are next. Does detting not feel like a missfire / full power loss when it happens then? Ed

It was misfiring above 4k rpm, also had code 34. I rewired the connector and reset the ecu, no more code 34, all clear. Changed the maf and the misfiring stopped on low boost but still there on high boost. Also got code 34 again! When it misfires i cant hear any rattling, its just total power loss. Im going to change the plugs next but its really starting to pi** me off! What percentage should my a/f be at idle and full throttle? Is my car detting?

nope, making full boost on both gauges. I think its dett as i got code 34 again which i didnt have this morning

Last time it would misfire above 4k rpm intermittantly and was down on power, it started after a heavy rain storm. Changed just the maf and it ran fine, but still gave the odd mis on high boost. Just overtook a mate, changed into 4th at 6800 rpm and all was well. Press the high boost button on the way back and got major misfire, switched it down to low and all ok again.

it could be the maf again as i only just jetwashed it! I didnt spray anywhere near the nose tho and its still ok on low boost, smooth and fast. I'll drive it to work tomorrow and see if its still the same.

OK since the maf sarga I changed it and made a splash cover to stop the air filter getting wet. Car runs well on low boost but still misfires on high boost. Can someone post up mickyb's number so I can get him to sort it out as im sick of it!

no seriously, did it make any difference?

was it worth buying tho vince?

id just want to jump off it!

boost leak?

checked for ecu errors?

I used them in my rover and they DID have an illlumiation wire, which makes them duller when the lights are on at night. I just left it off and had them bright all the time. Good gauges - i always use autogauge ones now, have el ones in the z.

Switch on the ariel remote lead, mmm good idea!

should be the same in all gears mate
