1815.0. "Montego ECU packing Up !?!" by NEWOA::BOSLEY (What time to go, Nah cant be...) Thu Jul 02 1992 22:23

    
    Hi,
    	
    	My Montego 1.6 Early 1986, would appear to be suffering form a Naff
    ECU (The Electronic Controler Unit - I presume they stand for..) The
    simptons are follows... 
    
    	Running On.
    	Choke coming on/off during a drive.
    	Doing an Emergency stop, the Engine RMP increases upto 1000 extra
    	
    The local garage although being very helpful (The Service Manager spent
    40 mins, under the Bonet checking..), finally stated that I
    should let them run the Full Check. - This takes 3 Hrs. - That
    translats to around 100 Pounds..  This should/but may not prove the 
    ECU is Naff. - Good Eh. I think as everything points to this little 
    bugger, I will just change it..
    
    	Does anyone know where I can get a `New' ECU from rather that
    paying Dearlership prices.. Also has anyone else had the same problem.
    
    Cheers,
    	
    	Stu.

1815.1	Blackbush motors..sold as seen :-(	ARRODS::BARROND	Snoopy Vs the Red_Barron	`Fri Jul 03 1992 13:58`	9
	Hi Stu, Have you thought about getting on off a wrecked car? You could try phoning up Blackbush Motors off the A30 between Hartney Whitney and Camberley. That only scrap shop I know of, there may be others that are nearer to you. Regards

	There is also a mod kit available that by-passes many of the regular ECU problems, including converting to a manual choke. JK

1815.4	Keeping your Cool?	PEKING::GERRYT		`Fri Jul 03 1992 17:29`	7
	Have you checked the coolant level?.... My VW started to play up because the head gasket was leaking and the coolant level dropped. Just a thought in case it's something relatively simple, to save a few bob!
1815.5	Haynes Fuel Injection Manual may help...	KERNEL::LOANE	Comfortably numb!!	`Fri Jul 03 1992 18:33`	3
	I have a Library copy of the Haynes Fuel Injection manual at home. I'm sure it has a troubleshooting section;...I'll have a look for the system your car uses and any tips available..
1815.6	NOT THE ECU.....	NEWOA::BOSLEY	What time to go, Nah cant be...	`Fri Jul 03 1992 18:47`	14
	Thanks Everyone.. I have checked a few things.. The Temp. Sensor below left of the Carb. is sending Duff info to the ECU. hence I get the Choke playing up. The engine run on and increase in engine RMP on sudden braking, is due to a very slightly leaking Head gasket. So it would appear that I have probably 2 or 3 duff SMALL Electronic units, rather than that Big Black ECU unit.... Yours Releaved, Stu.

1815.8	watch your wallet!	VOGON::KAPPLER	Spontaneity is fine in it's place....	`Fri Jul 03 1992 19:20`	18
	I hate to ruin your day, but you are replaying the scenario my father-in-law had with his Maestro. After changing the temperature sensor twice, they finally admitted it was the ECU, but that the only impact was on the choke, which in turn caused erratic running, poor fuel consumption, engine surging. My message must be, be wary of the opinions of "experts" trying to sell you bits! The choke conversion kits are widely advertised, presumably not without good reason! JK p.s. Scrap dealers also like to sell you used ECUs at large prices "Can't be anything wrong with it Guv, it's just a black box!"
1815.9	Thanks.. But.	NEWOA::BOSLEY	What time to go, Nah cant be...	`Fri Jul 03 1992 22:15`	13
	Thanks, BUT BUT my Grandfather & Uncle Both being in the trade have agreed, that the units playing up prove that ECU is Okay at the moment..... So I will go along with them rather than that of the BIG Dealer Networks, as I doubt very much if my relatives will SC**W me around. `However' we are not going to omitt the fact that the ECU could be Doggey, if So I KNOW A MAN WHO DOES can get it cheaper than the main dealers !!!!! So even then it will still be cheapish... Well ta again.. Stu.
