1) There is a big fat clunking sound, i think it's from the diff.. ? when i'm in 1st especially! sounds horrible, even though a few weeks ago the mechanic said the diff was fine.. maybe i stuffed the... gearbox ? Does anybody have any ideas?
2) After i've been running the car a little hard, as I turn it off the engine coughs and splutters for about 2-4 seconds jolting the car!! hmmm?
3) The car spluters and jolts in the morning when i first drive it, for about the first 2 km's.. not such a worry, maybe its a... spark plug?
4) When it rains and i turn on my air con, smoke comes out of the vents and smells like burning bush!
ok ok i'm only learning, so any ideas about whats wrong w/ my baby would be fuly helpful!
sik! cheers! sammy!
Heh I get the big clunking sound form the back end too when it drops up a gear (no acceleration).
Oooh and yeah my EA coughs and splutters for a while some times, did you notice that the RPMs when it does it are over 1000. I usually just let my car settle down for a minute before turning it off. But my guess fomr the smell of fuel is that it is running way way way too rich.
Dont get the spluttering when taking off in the morning though.
Anyway jsut thought I would let you know that you arent the only one with some of those problems
Yea, the engine is probably being overfuelled when u turn off the ignition. If its not at idle it will run-on for a bit coz of the excess fuel. I remember once when my throttle got stuck and i had to kill the ignition, it kept running for a few seconds. Was a bitch to restart too!

running on can be caused by many things, the most common being high idle or incorrect ignition timing, now before anyone says that it cant be the timing due to the fact the ignition system is off, incorrect timing causes the engine to run hotter, this can also cause certain parts of the combustion chamber/spark plug to heat up ( hot spots ) which in effect, causes run on.
Wrong spark plugs ( too hot ) can cause running on also
I would dare say she is running rich though as far as coughing in the morning is concerned
Lets go find that Hotdog tree I planted

Six in a row your absolutely right, the running on problem is a ignition issue, I'm pretty sure from advancing the engine too much. He needs to retard the ignition slightly so it doesn't run on. Also he should check his sparkplugs because the heat from the timing beingtoo far advanced can damage them.
