Firstly thanks to anyone who takes the time to read this, I’m not good at describing things like this. Had the car about two months now, a 2.0 Jts, it’s my first Alfa or anything like it, previously it’s been an old V8 and sundry run arounds mostly Polos, the reason for my post is that I’ve got a niggling worry that things aren’t right.

Firstly there’s the performance it doesn’t feel lively, it’ll accelerate fairly well at high speeds, but from a stand still it doesn’t feel as quick as an Escort.

Second when doing around 60 in 5th it really sounds, rather than feels, like it’s over reving and wants to change up. Bear in mind this may just be an engine note I’m not used to, as I say it’ll accelerate fine from there. Incidentally why hasn’t a 2.0 jts Gtv not got a sixth gear when other cars with the same engine has?

The car’s a 43,000 miler and doesn’t feel like it’s been thrashed, also it looks like it’s been well looked after plus it’s got a full service history. I’ve just had the cambelt, water pump etc changed on time (first time was at 11,000), at which point they also changed the plugs and two coils for a misfire. While that’s cured the misfire it still sometimes to pause very briefly whilst accelerating in 3rd. At the same time they replaced the coolant and since then the gauge has pretty quickly (about 2-3 miles of bypass driving) the temperature gauge goes straight up to just over 90, it never gets any higher even after a couple of hundred miles driving and often drops back to 90, the thing is in the few weeks I drove it before the work was done the needle never went over 90. The Garage who did it has got a good reputation in fact I got them from this forum.

Lastly while manoeuvring at low speed using the clutch the exhaust seems to rattle a lot, but maybe this is me.

Does it sound like I’ve got trouble, my fear is that I’m missing something that’ll do real harm. Would the more experienced owners here recommend a trip to somewhere with a diagnostic?

Thanks again for reading.

Hi mate, it does sound like something could be amiss. You really need to rev the engine though, it'll be pretty flat below 3000 rpm. If it's any consolation mine can be a little hesitant/jerky in 3rd when at low revs - no problems when accelerating on the open road though. The coils and injectors are common problems on the JTS; it might be worth hooking it up to Fiat Ecu or similar to check for any faults.

By the way, the 2.0 JTS has only ever had a 5 speed box :) And you will find it feels quite revvy on the motorway. The plus of this is that it pulls very well at high speeds.

As for the temp, it should sit at 90 or just below so I don't think you have any problems there.

Oh, that might be it. I've been worrying about screwing it so I've kept revs low, <3000 is my aim in fact. Can I drive it a bit harder then without harming it?

I realise that this might make me sound like a bit of a prol but as I say not used to this type of car.

Both the Twin spark and JTS engines need to be revved to 3000 and above to get good performance from them. The JTS has a lean burn and is reasonably sluggish (with a flat spot) down in low revs.

Yes absolutely! These engines need to be revved to get the most out of them. You'll be rewared with that Alfa sound and a lot more shove. It's not a particularly fast car the 2.0 but it's still very enjoyable to drive. Just make sure you check the oil religiously and keep it topped up to the max mark with 10W 60 - you will regret it if you don't! Driving below 3k rpm should make you a saint but seriously give it some more if you want some fun.

I've just popped down to the next village to Tesco to give it a try and fair play I see what you mean. Had the sound and the extra poke I've been looking for.

Cheers both, very much appreciated.

By the way I'm checking the oil weekly

I am surprised to read this about owners considering the JTS engine as being sluggish at low revs, the very first thing that impressed me on my test drive before buying my car was its massive low down torque compared to my previous 2.0 Twin Spark. However I did find the Twin Spark to be more fun at higher revs. Indeed, I have had the JTS remapped in an attempt to get more upper end performance, but most of the improvement has turned out to be at below 5,500. It is now very easy indeed to set the ASR lamp flashing when pulling away from a standstill, and I still use the same type of tyre, Toyo T1R, as I used on the 2.0 TS 156.

I've been wondering about a remap myself, to improve the low down drivability. Can I ask where you got yours remapped? I know the JTS is a little different when it comes to this in that not many people can remap it. Would you say there is a definite improvement / would you recommend it?

Alfa Tuner, you would need to contact him yourself about the price. I also have his cat-back, larger than standard diameter, stainless exhaust fitted.

The real improvement is the driveability at lower speeds, which Gus pointed out to me when I contacted him. I consider it worthwhile for both the remap and the exhaust, but neither are cheap.

I agree with everyone else ,you will have to rev it to get the best from it,and below 3000rpm it does feel a little sluggish,but i wouldnt change mine for the world,once you get on a nice winding well surfaced road and open her up you will see what we're talking about,the only serious recommendation i would offer is to check the oil level religiously ,and only use top spec 10w/60 oil....enjoy.:cool:

Firstly what's 'remapping'?

As for the original question I've driven the car a little harder tonight and noticed a massive difference, more than enough to keep me occupied to and from work.

As for the other uses of the car, apart from realising I've bought the wrong oil, I completely agree with everything said in the above post. I'm lucky enough to live about half an hour from some great roads, and last week had the chance to take it for a good few hours in the mountains, even though I had my concerns about driving about in a reasonably urban environment out there it did come into its own.
