Video of my S12 sounding drunk... help!
 

JackieFan asked for me to upload a video so I have...

http://www.vimeo.com/11904610

ive bought a set of those ignition spark testers: http://www.halfords.com/webapp/wcs/s...goryId_165469#

the result was that im getting a spark to all the cylinders...

ive the dizzy cap and all fine...

unplugged and plugged in injector leads...

replaced the coil lead...

replaced the coil which had cracked somehow...

checked the spark with that HT tool and all the plugs light up...

next on the list is checking the spark plugs...

what else could it be?

Stoned post! ok so you have spark, and its misfiring. fuel and compression tests next.

get an automotive bulb a resistor with the same impedance as the injectors [sevice manual]and some wire, disconnect the injectors and connect each injector wire in turn to the bulb, and crank the engine. light = ok, and vice-versa. Give that its running atall can assume with reasonable safety the ecu is fine, and inconsistent readings here wouldindicate some bad wiring

for the injectors themselves, download the service manual and refer to the fuelling section for the test [you'll need a multimeter]

oh... where can i get one of these british shed inventions? :-)

Maplin/RS and your local motor factor [not halfrauds]

i have a multimeter already... what about the other invention? is is called something as a complete device or do i buy parts?

sorry im on a learning curve here.

cheers

erm, well theres a special tool which consists of those bits, god knows what they called it though. I'm not into paying excess if i can heath robinson something together. the resistor and you multimeter on continuity mode would do the trick in most cases too.

Is it just my PC or does it sound like that's not missing once the engine actually gathers pace?

You could also try checking the ECU for fault codes.

lo-fi web video doesnt help, but it does seem less pronounced, hence the compression test.
