Solved a serious problem today by accident. Some work had been done on the car several weeks ago and here were the symptoms:' Car runs fine until it warmed up. Then it bucked on acceleration and sometimes stalled taking off from a stoplight. Check Engine light came on with multiple codes for engine ...

Many thanks to Lee for his comment. I had actually taken a thorough look at the wiring running down the trunk like arm and it looked good. After his post, I took a look again. This time, I cut the webbing that covered the group of wires so that I could slide it down and see the wires themselves. Sur...

I have a '96 Volvo 850 that I bought recently. It had two fobs and 3 keys including a Valet Key which I understand will only open the doors, not trunk, nor glove compartment. The trunk will not lock/unlock when I use either the drivers key nor the remote. Everything else locks/unlocks as I would exp...

I had an erratic cruise control....sometimes it would work. Sometimes, it just ignored my requests to set speed. When I first got the car a few years ago, I was having this problem. I replaced the control module on the firewall with one from a seller on EBAY, so it was used. Cruise worked fine up un...

It all depends on knowing. If your cylinder lock is getting hard to turn, it is most likely simply wearing out. To replace: 1. You must have the key 2. You have to push a small button in right up against the metal dash on the side of the key switch. The size of the keyswitch narrows in the area of t...

Well....at last. Here's the secret to my confusion: This problem all began with an overheat due to a blown head gasket. The trip the cylinder head took to the machine shop to be milled resulted in damage to one of the temperature sensors still screwed into the head. When the temp gauge would not reg...

Bill, Let me clarify a typo: The check engine light is NOT on. Both A1 and A2 show 1-1-1 codes. From a post I read on the birckboard last night, there are two engine temp sensors on a 95 940 w/o turbo: I confirmed this by scouring over my wiring diagrams. Both sensors are under the intake manifold s...

Sorry for the long delay also in responding. I'm getting no codes from anything on this car...neither A1 nor A2 testing gives me a code. The check engine light is on. I ordered and put in a used fuel control module and, the first time I started the car, the gauge read and the cooling fans came on. W...

The thermostat is not the problem. The radiator is hot, the engine overheats after a long time at idle due to the cooling fan not running. I found the fan relay very near the battery and jumpered the 12v to each of the red and green leaqds going to the fan. The fan runs on both speeds. So, it apppea...

The problem was the gear position sensor (also known as the neutral switch) mounted on the transmission. I decided to try to repair it since it was clear that the unit could be taken apart. I fixed it right on the transmission although I had to physically remove it from the transmission (the electri...
