Hi there, A little history, have had this car since 2000 and have taken care of it. Did the PCV change, cleaned the sump 3 times. A couple of weeks ago had the oil pressure light come on. Cleaned the sump again (about 30% clogged with bits but not sludge and nothing metallic) and changed...

Hello i have noticed some missfire at idle since some days. can be ear at the exhaust as small puf puf sound. it occure when the engine is hot, only at idle, the counter can reach 150 missfire on cyl2 after 38km of road. No missfire when i drive, no at full load or even at light load, only...

Yesterday, I was driving my '95 9000 2.3 CSE through Oslo in heavy traffic, meaning i used one hour to get 5-6 kms... Anyhow, after about 45 minutes, the idle went crazy... jumped up and down randomly, varying from about 1500 to 2500 RPM ..... Made it kinda hard to drive slowly.... :crazy...

I have just replaced a couple of vacuum pipes which were loose on their connectors. (The one from the back of the manifold to the cam cover with the one-way valve on it) Before starting this I took out the IAC and gave it a thorough going over with carb cleaner and left it to dry. When I had...

When engine is cold its OK, but when it warms up it feels like a miss. New plugs, still the same. Pulls fine under load, DI should be good. Checked vacume lines . Am I missing anything ? Thanks for any advice KB

Having finally started my '96 Aero after 3months non-use and a great pile of new parts for my GT3071r build - started on the button but idle isnt happy. Starts fine, but immeditately idles too high from cold. Pinch the IAC hose going to intake after throttle body (on the top) and the revs drop...

Hi, just bought my first Saab and to be honest, very pleased with it. But, when I turn the air con on, the engine idle goes up and down and feels 'lumpy'! I know that the compressor kicks in and changes the engine speed but should it be like this? Need to know as I have warranty for three months...

Today I noticed that when I'm idling at a light, my boost guage fluctuates in the green; the rpm guage is not doing the same. I've also noticed that when boost is applied during normal acceleration (2-2.5K RPM max), it seems to sit in the yellow a little more than usual. Could my turbo be...

What causes the idle to sit a little high then slowly drop to it's 850rpm level. Only sometimes. Cruising along knock out of gear and idle speed hovers 950-1100rpm eventually settling. Same at junctions. I have cleaned throttle body and new idle control valve fitted. Fairly recent lamda also...

Just replaced my throttle body with recon part! Loads better engine magement light off now. But after warmed up it seems to intermittantly rev like a small blip on the throttle. Also when you push the throttle down its slow to react on the first bit. So when you change gear (its a manual) and...

How does the idle control valve work? Does it use 12v to move or is it variable voltage? How would a dodgy one affect engine @ wider throttle openings? The resistance between the two terminals on mine is 8.5 ohms, good or bad?

Thought I would take the old faithful for a run this morning seeing as the wife has the car on a permanent basis now. I noticed immediately that the tickover idle is arouns 1200 rpm and it seems to be be rough too. It's almost as if the car is rocking slightly!? The rev counter does not seem...

Hello - I'm a new Saab owner - bought the above car about 3 weeks ago. Just over 100K but with full Saab history. Impressed to start with - I've had a few different diesels and this 2.2 has a nice turbo kick and feels quite refined at speed - but sounds like a tractor at idle... not that it...

hi new to this site i have a 900 classic lpt 16v problem is when im sitting in traffic or lights for a set length of time it trips on to engine check but if i turn the engine off for a couple of minutes the start again its away when driving everything is ok only when i sit idling any ideas please

I'm having a very odd problem with my 2001 2.2 TiD and just wondered if anyone else had experienced anything similar or had any thoughts on what the cause could be. A week or so before the 66k miles service was due the engine warning light came and the car went into limp home mode. Switching...

Hey guys, It's me again. I just noticed that the car is idling horribly at first start up. It goes through a phrase of leveling at 1,000 RPM and bottoming out to the point of almost stalling. What could be causing this? It seems that after everything settles, it's fine but at first its bad, and...

1993 MY 9000CS 2.0 LPT I had a problem with my 9000 cutting out once after starting from cold. I cleaned the IAC and it seems a bit better now. However, the idle speed is not constant and varies by a small amount at tckover, between 900 and 1000 rpm. Also, when I blip the throttle, it almost...

Hi all. Another problem I am afraid. The car has a very fast idle of 1500rpm. We have changed the idle control valve with one we know works. The problem is not constant. Sometimes it idles at the correct speed and other times it races away which in an auto with dodgy brakes is not good!! We...

hi guys i have a 1996 aero with some idling problems...with the IAC plugged in i have a higher than normal initial idle flare then she seems to idle fine (around 800-900 rpm's) but when i give her gas a very rapid idle fluctuation starts 1500-2000 rpm's i thought i would just nurse the car home...
