Hi All,

I stuck a post up a while ago about high tickover on my HGT, turned out to be a split in the intake pipe behind the MAF so the fueling was all to cock! Fixed that with a new pipe and all was good, for two days :(

Since then, every morning is a case of starting the car, pull out of the driveway (steep uphill), stall. Restart, stall. Go to restart again and it just turns over whilst attempting (weakly) to fire.

Once it starts it stinks of unburnt fuel for a couple of seconds and then it's fine for the rest of the day. It's worse when it's cold and it won't do it if I leave it running on the drive for a couple of mins before I leave, not wise round here as a chav'll have it away in minutes!

I've checked for leaks in the intake with a can of WD40, cleaned the MAF with carb cleaner which improved things a little. I've also found that a little oil has been pushed through the breather pipe and has contaminated the little pointy sensor just 'downwind' of it, cleaned that (anyone know what it is?:confused:) and put it back in - no improvement.

Other than that it runs sweet!

Any ideas guys and girls? - I'm fed up with pulling out of the drive only to block the road for a few minutes - it's quite embarasing!!

Cheers

Hi, I would check FUSE box connector and earth points at first. I dont know exactly if it has same connector as 1.6 engine, to be sure just follow wires leaving fuse-box and take apart and clean with wd40. Also earth points can be corroded.
 
Hi,

I've been out and checked the earths, fuebox and most of the relevant connections but found nothing unusual. I added a couple of extra earth straps but that was back last year and they are still well covered at the ends with thick grease.

I've got a feeling there is a sensor on its way out and it will soon give a fault code and show me which sensor it is! I've ordered a water temp sensor and the other one I mentioned earlier turned out to be an air temp sensor, will swap these out and see if it makes a difference.

Thanks

Hi I don't reccomend buying things until you are sure. Its endless story then. Connectors my look ok, but if you take them apart you will see sings of rust there. It's possible that overfueling cooked your spark-plugs, so you can take a look on condition of them. Did you do ecu reset after hoses were fixed??

All the connectors have been checked, cleaned and put back together. I've been out this evening and changed the plugs for a set of NGK BKR6EKC, as I don't know when the plugs were last changed, already it feels better but I'll have to wait until the morning to see!

I'm changing the coolant temp sensor as I changed the thermostat last week and the one that was in there looked a bit corroded, the previous owner probably just run it with water rather than coolant!!

I must admit I didn't think to do a reset after changing the intake pipe, I'll do this as well.

Thanks for the responses, I'll see what happens tomorrow.....
 
UPDATE!!

After changing the plugs last night, I found that the rocker cover gasket had sprung a leak into the third plug well. Since cleaning the oil out, replacing the plugs and resetting the ECU it runs........................LIKE A DREAM:slayer:

Going to change the coolant temp sensor later as I have one here anyway and see if that makes it any better - doubtful but it's worth changing for piece of mind;)

Upon inspecting the plugs that I took out, they were all a reasonably healthy colour but one of them had a conductor missing, they were Bosch super 4's, this one was a not-so-super 3!!!

Cam cover gasket set found on fleabay £10 :D

Thanks to fiat37 for the replies!
