Well from what i read, the ECU adapts to your driving style after a couple of hunded miles if it's been disconnected. Says so in the Haynes manual. So if you reconnect it, then drive around, eventually it will get itself operating as usual, learning the essentials, engine speed, road speed, intake ...

cant beat a good drive out in the hills and country lanes,,especialy when its raining,,im a bit weird i actualu quite like the rain

p/s nice car mate

ok thanks ,,what if i disconnect the ecu i have pull the plug out take it off try another,,if it dont work will mine go back on ok,,i mean diconnecting wont loose its memory,,i suppose its only like dicoing the battery

thanks.

sorry mate the main ecu to control the engine,the one in the kick panel on the drivers side

my windows have a mind of there own,,in my case they wont stay down,,it only happens when it rains,,somethin to with it coming it a bit on the passanger side foot well,,i remember somone haivng trouble with the windows on another forum yr or so ago that turned out the be the total closure on the dri...

do you want the part number if you mean its c16nz2 engine and part is 16204859 HR on it

heres somthin you may know if i stick an ecu on the car im told it needs programing,do you know if its because of the immobilizer??

only reason is i bypassed the immobilizer to fit an after market alarm you see

that is on the cards,,im going to try as a very last resort,EGR from scrappers,,cant source a blanking plate,an ecu if i can source the same one,scrappers quoted £15 if they have one and a cheap lambda,,though the lambda doesnt kick in till the engine is warm,so wont explain the rough start from col...

Hey craggles, just though. Have you checked the intake valves? You mentioned the EGR valve, but what if one of the main 8 valves are blocked up? It happens, so you never know. Just a thought :wave intake valves as in the ones in the head mate? nothing is just a thought bud,,im open to any suggestio...

hi mate thanks for your input,,mine is the single point injection model,,i checked through all the pipework on the car,,im 90% sure its in the engine itself,,so the head is coming of it next week for a look as to why cylinder 4 is lower on compression,as a last resort im goin to try and source an EC...

LOL yeah if i know ill mess with it over and over and it will just sort itself,,what makes me work at it so hard with this car is peoples comments on the condition of it,well mainly MOT stations..

ive been goin through the WIP on here and there is some minters

Well just if anyone wants to know,,so far the car is running rough only in the morning now,,i changed the SPI unit today as i took the car to my mates works and it is blowing black smoke so over fueling it think,is that the reason for it starting rough in the morn,weting the plugs up maybe.. anyway ...

I've owned a number of cars myself, but i just fell in love with my Cav the day i bought it. :D anywho, about that hesitation... where on earth is it!!!! :shock: :lol: cant be that hard to solve :lol: I'm sure it'll either sort itself out or you'll find a way :D Cheers dude :grommit hope so,,got up...

its on the list of the next thing to do the crank sensor,,interesting that you say that with yours,,i defernatly give it a whirl i went to the breakers yard this morning and got the injecter,idle control valve,throttle possision sensor and a coil of a cavy,,still doin it im affraid,,howeverthe ilimi...

no problem mate thanks alot anyway for trying,youve been a great help and so to the others,ill plog along and see if i can sort it out,,new coil,leads and blank the egr valve of to see if it does anythin. by the way have you ever removed the crank sensor,think its front engine bottom to left as you ...

well that would sound almost like faulty injectors or fuel pump. Tried giving her a nice long run with plenty of fuel additive? Cant put my mind on what it could be. :? if it was faulty fuel pump or injecter would it show up as weak or rich on a c02 machine? i give her a nice run down my mum she li...

i hope not the ECU,,i tell you what i have noticed since i cleaned the injecter out the single on top,,its ticking louder :scratch :scratch i only gave it a spray with cleaner..maybe it was always ment to sound like that,,there is plenty of presure on fuel there,,as i undone the torque bolt to re-si...

Hi mate :wave Just a wild guess, but could it be the engine ECU itself? It sounds like you've checked over all the possible suspects and it sounds to me like its something electrical now :scratch Just a thought :) Andrei Hi mate,,not thought of that one :scratch though i did the paperclip test and ...

have you checked any of your inlet/breather hoses to make sure they arent clogged with cak? Hi mate thanks for replying,,ive checked the top one on the rocker cover and all the small hoses around the spi unit was taken of and blown through to check,the one going down the back into the manifold not ...
