Whenever I come to a halt quickly, usually traffic lights, or slow down quickly for a turing my Zed tends to stall if I don't dip the clutch at the last minute. It will also stall blipping the throtle to over 3k and letting off. the revs just keep dropping :(

 

Now I've gone through the archive's and figured that it's the TPS. Soaked it in WD40 yesterday and it sorted the problem temporarily until it dried. Got some solvent cleaner today and attacked it with a toothbrush (did the CAS too :D ) but although it's made it better it's still happening.

 

Opinions please? Did I do a sh*t job of cleaning it - it's not green anymore, or do I need to whack some copper grease or something on there?

 

James :confused:

Jaffa,

 

have u tried cleaning the Temp sensor connector, at the front of the engine bay. that tends to decay and cause loads of probs....

cheers guys, looks like I'll be cleaning a lot of sensors tomorrow :)

 

PS Idle is smooth at 750.. if I try to upset her by blipping the throtle hard at stand still it will go 3k down to 50:eek: (or stall) then back to 1000, drop to 900, then drop to 750.

ohh, and don't know about the A/C, don't have it on much. I'll try it out later.

Cleaned TPS (again), and temp sensor - no difference.

 

Printed out the IAA stuff and had a go. Bit of a sod to work with, and I only got as far as removing the connector for the AAC. It was in a right state so cleaned that up. Couldn't get my hands around the FICD enough to remove connectors.

 

Did notice that the rubber surround on the connectors broke as I was attempting to wrestle them free :(

 

Put it all back together, started her up and she's a bit lumpy, bit I figure that was down to the battery being disconnected. Blip the throttle and the evs dropp all the way back then she stalls :( look around and there's a plume of smoke behind me :eek:

 

She's now smoking all the time, more smoke with more revs, tries to stall after any revs above 1,500. Tried the air con, and she nearly died (never did that before).

 

So I'm figuring I've broken the connection to the FICD, I'm pretty sure everything was put back properly, the AAC made a connection given enough fiddling, not sure if it stayed though.

 

so after all of that - HELP!! would this be the cause of the smoking too? Not seen any smoke before now.

OK calmed down a bit now. Going to strip the whole uniot out tomorrow morning using a guide from twinturbo.net, give it an overhaul then put it all back.

 

Hopefully taking it out properly will reveal something I've left out

It really helps to have a ConZult/Techtom when you start messing with these things. Then you can see the values being passed back by the sensors and you can usually identify the cause of the problem, without taking everything apart.

Saw that, something to do with worn springs. Will try that next if this doesn't improve it. Thing is mine will stall if you just let the revs drop from above 3k ... well used to, in it's current state it'll stall if you look at it funny! LOL

 

Might have to search out a Conzult over the weekend if I don't get anywhere tomorrow - there will of course be beverages of choice in return :D

 

Thanks,

James

Hello James,

 

I'm over in NW London, near Brent Cross. I've got a Conzult if you wanted to head over.

Start the car up this morning to move her out the garage so I can sort the problems out from yesterday. Being quite gentle until I realise she's fine:confused: :D

 

Revs are stable again, doesn't stall easily ( not sure if my original problem has been resolved though) and behaves normally with the AC being turned on and off.

 

Smoke has nearly all gone, but still had a little white smoke on the drivers side, but I'm hoping that's condensation on startup as there's some water in the exhaust tip.

 

 

Still wouldn't mind checking her out with a Conzult though - Vijay you have PM :D

 

Thanks

James
