Sounds like fuel starvation. Would suggest cleaning any filters in the fuel line or replacing.
Also check the stop idle valve. This should be inline in the air intake pipe to the intake manifold..
Remove it and clean with WD40.Make sure you note the orientation of the spring.
To reset the ECU disconnect the battery for 5 minute the reconnect. The ECU should reset to factory settings. Make sure you know radio and alarm codes!
Try petrol additive STP or Redex to clean inside the engine.
Thats as far as my knowledge goes, hope it helps.

Could be, but you will need to check for trouble codes, since the engine light came on. The code or codes may help you troubleshoot it.

I have a 1999 volvo s70 non-turbo 2.4 5 cyl. I bought it 1 year ago with 124k. It runs great, but the a/c cuts off when it gets over 90 degrees. At freeway speeds, it stays on (until it gets around 100...


There have been a lot of problems with the compressor cutting out when it gets hot. When the A/C begins to blow warm, check the power supply wire to the compressor. If there is power in the wire, you will most likely have to replace the compressor. If there is no power, you will have to trace it back to see what the problem is (a wiring diagram will help greatly).

Air conditioning works when car first starts up (Volvo s40) then stops cooling after a while (usually when I am stopped in traffic) -- then if I turn it off and back on after a few minutes it works again....


It sounds like your cooling fans are not working.Need to check the cooling fan fuses,and the cooling fan relays.There is also a high side switch mounted somewhere on the high side of the ac system that cuts the fans on,or kicks them up on high speed when the ac system gets to high on the high side of the system.This switch may also cut the compressor off.I would check the fuses and relays for these fans first,this is more likely the problem.Is the car running normal temperature? If not the fans may not be running at all.Have them checked.The fan or fans may be bad them selfs.If I can be any more help,let me know.>>roniecon@gmail.com

Engine starting problem


Hey Lindypop,

If you have another ignition key, I would suggest trying that key and see if the problem persists. The key has a micro-chip in them that allows the key to work in your vehicle only, and you may be having a problem with one of your keys.

If this is the case, a fault will be stored in the engine computer. It will be a good idea to check those codes and address them as necessary, it may help to avoid getting stranded.

Good Luck!
