newbie, with GDI ????
Hello all,
my volvo s40 GDI has started to develop some strange symptoms..
1. it will be sitting idiling at 620rpm and then it will start reving from there gradually up to 1500 rpm where it then drops down and stalls, this normally happens daily but not every time at idle.
2. normally just after driving 1-2 miles after starting the car up in the morning the first time I start to accelerate harder the car seems to just stick at that speed, the revs slowly build up and then past 4k rpm all is ok.
3. loud ticking coming from engine, strange thing is it is not there all the time, follows the revs of the car when it is there but it will start very quietly increase to a cresencdo and then silence. 5 seconds later you have the increase to cresencdo and then nothing again it is not there all the time.
Apart from this the car is great, should say it is a late 99 with 47k on the clock. All help welocme.

RE: newbie, with GDI ????
Hi,
I have a 2000 1.8i GDI, 78000 miles.
I've had the same trouble for a few months.
I also get the low RPM and wavering speeds at idle. Some two months ago it was cutting out frequently.
I find that driving in heavy traffic and stop start driving makes it get worse.
I've tried a number of things to remedy this:
Fuel additives, namely STP injector cleaner. Appears to run better with this in the tank.
Decarb spray, no real difference, although I dont think I did it properly.
Drove at 120kmh in 3rd gear to burn out carbon, This seemed to do the job for a day or two.
Got the car serviced about a month ago and it is running much better, I think the new oil is the difference. I've read that an oil change should be done at least every 10 months. The GDI is apparently not good with european fuel, leading to carbon buildup which affects the injectors.
If problems get worse I'll try and get the fault codes, maybe try new injectors and coils. Let me know how you get on.

RE: newbie, with GDI ????
A bit late, I know. I too get the same issue with my revs wavering increasingly until it stalls with my GDI. Heavy stop start traffi makes it worse for me too. A dealership service always sorts this out for some reason, not sure why.
The ticking noise is characteristic for the GDI engine and normally should not be a concern. From my understanding, the reason it comes in and out is because of the engine switching injection/timing modes.
I too find that an injector additive makes a big difference to my engine's performance. I get power loss around 3000 rpm and additive cures this for a bit.
Hope that helps.

Does this car really have fuel injectors or a carburetor?

I found this Ford site that references the natural aspiration ; http://media.ford.com/newsroom/featu...?release=15580 go to the 7th paragraph.

RE: newbie, with GDI ????
Right - easy to explain: naturally aspirated means that it doesn't have a turbocharger or compressor/supercharger. A naturally aspirated car sucks in its air by means of the vacuum created in the downstroke of the piston. Aspiration is the sucking in of air, not fuel. It's not related to whether the fuel is injected or introduced with a carburettor. Hope that clears that one up.
I did see one strange thing in that Ford page though. Explain this one if you can:
How can it be simultaneously shorter and longer? [&:]

The new S40 is almost 2 inches shorter than the outgoing model, but also is wider and longer for increased stability and performance.

Good point - maybe somewhere in the quantum world shorter is longer!
But the answer is in the Ford article for me: ". . . the S40 is powered by a 2.5-liter, 220-bhp five-cylinder turbocharged gasoline engine; a 2.4i or 2.4-liter five-cylinder naturally aspirated engine with 170 hp and 140 hp, respectively; or a 2.0-liter, 136-bhp four-cylinder turbo diesel engine."
thks for helping to clear that up for me for aspirated mode in the nonturbo version apparently. So I guess I need injector cleaner if this happens on mine!

The only reason I can think that the car can be shorter and longer is if the whole car, body and all, is shorter but the wheel base is longer, i.e. the wheels are closer to the front and rear of the car. You can spot the marketing speak though, can't you!

RE: newbie, with GDI ????
Hi i also had a volvo s40 2001 gdi 55000miles, i don,t have any problems with it idling but i have the ticking noise in the engine its always there and very noticable its been there for as long as i had the car and obviosly have no adverse effect on performance whatever it is,
it more or an irratant, i had it in the dealers for another problem, and he told me about the gdi engines if there not driven hard from time to time carbon can build up in that engine at about 60000 miles causing a reving a stalling issue,
just that i,d let ye know

RE: newbie, with GDI ????
Did you ever get your tickover/revving/stalling problem sorted.
mine is exactly the same and i'm just about to set about it with a large hammer.
found one thing out. if i disconnet the knock sensor on the camshaft it ticks over sweet at the correct rpm....
117000 miles 1998

RE: newbie, with GDI ????
I had the unsteady idle along with random misfire also if stopped in very heavy traffic on and off for awhile with my '02 V40. Also would get the misfire + hesitation upon hot starts at different times.
Ultimately cured with 2 new coilpacks. Read here and other places about the coils overheating, cracking and causing these issues.
Pulled the packs and sure enough, one of them had a nice, slightly larger than hairline crack running almost the full length of the shaft.
