poor running

[mycroft]

Only had my car a few days so not used to it yet so taking it very carefully .
Went for a run today , only about 40 miles each way , car ran really well .
Turned off for a while maybe 20 mins and when i started up again she was running ruff , kangarooed down the road carried on thinking it may be me being a crap driver . It ran but didn't feel right bear in mind I'm not that familiar with it yet . Thought i might have bought myself a pup really worried . After 10 miles pulled over and gave her a few mins rest , started up again and it felt like a different car .
So i assume the car reset itself some how .

What did i do wrong ? should i be worried .

Should this be on T350/Tam forum ?

Thanks

Mine does this though has been better of late. When started with the engine warm, it struggles to start, idles lumpy and so stalls if you take your foot off the gas. Also the gas pedal becomes very sensitive. Get a smell of petrol as well.

However, after 30 seconds or so it's fine. Because of this I haven't really looked into what the problem is yet.

I've also had this experienece with mine. Would be interested to know what the cause is.

The slow turnover when warm on mine seemed to go away by itself. Only thing I can think is that the battery charge was a bit low and after more regular use it was OK.

However, the smell of petrol after a warm start continued, until it was found that one of the two throttle potentiometers was faulty. After this was changed the petrol smell went away and it ran slightly smoother - less engine braking effect was the thing I noticed the most.

surprised to see this again i Had forgotten posting it .
i found the problem happened when i started from warm and the immobilizer had cut in so i had to reset it , i tended to do this by pressing the key fob not by inserting the peg in the dash and i realised i was turning the key while the fuel pump was still running up . I don't know how this was causing a problem but simply waiting a few seconds for the pump to prime its not happened again .
Hope someone can explain what was happening .

I've had the same problems. The engine was running smoothly sometimes, rough at others (always when cold) and in any case the car was almost impossible to drive slowly (up to around 40mph) without serious juddering.

Last week I got the Omex engine management upgrade installed at Racing Green and it completely transformed the car. I can now start the engine from cold without using the throttle and it just runs. When driving it is almost as if it has more torque, the car will pick up speed from low revs much more easily. But best of all, I drove it (or rather, crawled) around central London in heavy traffic - the engine was smooth as silk!

All they need is proper servicing, starting the engine from cold without using the throttle is how it should be done. They dont need an OMEX for that!

Each to their own. Outside major cities, where you can just go and drive, it's probably less of an issue. But in my case, it's nice to not have to heel-and-toe anymore every time I arrive at a traffic light for the first 5 or 10 minutes after driving off (and in London, that happens a lot).

Like I said before, a correctly serviced car should not have needed an OMEX to correct poor or out dated servicing.

As far as I know, you have never driven my car, checked the engine, or seen the service book. It gets looked after very well, thank you.

Did it need an Omex? Probably not. Does it make a difference? Oh yes, a big one! The engine is just much smoother and more flexible now. That might not be for everyone (for whatever reason) but I love it.

I mean, my Tuscan didn't need carbon cans either, but they sure make the journeys more fun!

As you say, I've not driven your car etc. My point was you don't need a sledge hammer to fit a panel pin Glad you're happy with your service book stamps.

So, youre saying Arj's car is poorly serviced?

No, I said a properly serviced car should not need an Omex fitted to run well. Normally cars that are due a service, or a tickle on the lap top display the symptoms noted.

The ECU does not always complete its complete cycle until after the pump has primed.

Can cause ECU malfunction and poor running, simply switch off ignition, wait 5 seconds the slowly select ignition wait for pump to prime and then start.

Don't drive the poor thing, as you will be damaging the engine and catalysts

As others have said above; 'correct' servicing & set up will ensure corrrect smooth running & idle between service schedule.

Thanks , reckoned it was something like that .
Had the car nearly a year now so getting used to its idiosyncrasies .(sp)
