Question about 1982 Volvo 240 Series

1 Answer

Car idles rough, rpms start at normal, then go down, and repeat

This does not happen when the car is warmed up, or even in the mornings. I have noticed though, that if i leave the car for an hour or more, when I start it, the rpms go up to normal, then down to where the car almost dies (and has a couple of times), then back up, then down, and so on.

Also when I let the car warm up in the morning it sometimes starts to happen. I've replaced the distributor and cap now, and am going to replace the wires and plugs as soon as I can afford it. Is that the only problem, or is it something else?

You could have a vacuum leak or the map sensor is going out.

Rough idle


Sounds like a automatic choke sticking....Take the air duct loose from carb..While accelerating engine spray bottle throttle spray in.....as the car tries to die...stop spraying...Repeat 3 or 4 times.....It will clean your injectors. Runs alot better...Remember....bottle throttle spray...not carborator spray

TO WHOM IT MAY CONCERN:
My car will not idle properly until after it is warmed up.(1995 Olds. Cutlass Supreme 3.4)
It wants to idle up and down between 1000 and and 2000 and will stall out if I don't keep it revved up at 2000 until it warms up.
Thank you and have a great day.

Try unplugging the mass air flow sensor and see if it levels out.If so I would change the mass air flow sensor.If not try the same technique with the throttle position sensor.

Car starts poorly during cold mornings. The idle


Sounds like a cold start valve (which is actually an additional injector in the intake to assist in cold starting) If you can get it to your local prts store while the light is on they will read the codes for free and tell you what the car thinks is amiss.

Computer reads multiple misfires rough idle trouble starting


The air fuel mixture sensor is probably starting to fail. You need to have a simple diagnosis done at the shop and then have it replaced - they are usually not much a reputable mechanical shops. When the motor warms up your air/fuel mixture changes hence the rough idle etc. Hope this helps.

No Heat in 99 Taurus


Just finished fixing my daughters 1999 taurus heat. It would blow warm only when running down the road. At idle it blew cold. I started with replacing thermostat, and water pump because they are the easier fix. Still did not help. Then I replaced the heater core. A daunting job but not that hard to move the dash slighly out of the way to replace. There is a good write up at tarusclub.com. After that, heat was better but at idle, it would still blow cool sometimes. Researched and found answer. Park car on the steepest hill you can find with front of car up. Start car and take off reservoir cap. Let car warm up and keep rpms about 1500. After a while the fluid will come running out of the car and all over the place but it will bring air bubbles with it. Reduce rpm, add more fluid and repeat about 3 times. It will make a mess but after that, the heater works perfectly. We get heat long before the temp gage indicates any and it never blows cold unless you lower the temp.
