Hi All

 

Been a while since i posted, My Zed is having some issues at the min. And hoping for some advice before the weather clears up and i can get into looking at it.

 

It was an NA Auto now Manual with TT box, clutch, etc. recently it has been doing a few things.

 

1 I have the boosted master cylinder etc installed and adjusted for when i fitted it, If i start the car with my foot of the clutch the car tries to move even when not in gear. if i rev the engine a bit it will try to move under its own power.

 

2 when cold is now difficult to engage 1st to 2nd but gets better as it warms up.

 

3 Tps is set to .45 and when i back of the throttle it pops out of the exhausts like a race car.

 

current Mods are

 

stainless manifolds and divorced decats stainless all way back.

Air filter K&N

 

I dont have a consult to test on the car, but ecu test comes up with 34 knock sensor even with new knock sensor and hard wired into loom.

 

Any help or advice would be grateful i will be doing compression test and new plugs when weather is better to see if this helps

 

Cheers Nathan

Hi Nathan and good to hear from you again. Sorry I cant help but hopefully someone will be along soon :thumbup1:

Your clutch biting point is too high, ie the plate is not fully disengaging hence why its trying to pull away, it could be seized or the wrong clutch.

You can still use an NA clutch assembly with a TT box.

Wouldn't it be too low? So even when you dip it it is only half letting go?

 

I had a problem with my Capri where loose gearbox bellhouse bolts caused similar issues. Very difficult to engage first. It just wasn't all in line properly and was a bit too far apart.

Yes too low soz, i knew what i meant lol, although its probably not the pedal at issue but the clutch plate or try re bleeding the slave and check the pin is moving far enough to dis-engage it

RE knock sensor, i too had a new sensor when i fitted my engine but still showed code 34, so put the resistor back, its most likely the crappy cheap sensor from ebay thats no good.

what kind of gear-oil are you using in the box ? sounds like it's too thick (when cold)

I was wondering that too, good thinking, so thick that it is transmitting torque.

cheers for the replies everyone. clutch master and slave were removed for the car to be bled and has a one piece line. am using a TT clutch, flywheel and gearbox. unsure what oil is in it as cant remember what i put in. what would be the ideal one to use and will do a change of oil.

 

Clutch pedal does bite low to think about it. but am going to check and adjust when weather clears.

 

Knock sensor was an ebay one a few years ago, what resistor was it for the bypass will try that and order a new knock sensor. 1K i think ??

 

The clutch only seems to hold and the car move on starting, that is with my foot off the pedal. and the change of 1st to 2nd is worse when cold. thought it might be clutch not releasing fully when i goto change as if I hold the pedal down for few seconds it will then change easier.

 

Cheers Guys

The resistor is 1 mega ohm (1000K ohm)

cheers Groover

correct oil for the manual transmission is 75W90 GL4 (box takes a little under 3 liter)

Excellent thanks Lymon
