So here's the deal, I bought this 93 Volvo 940 turbo station wagon about a month ago. It was stalling when I got it so I replaced the rotted hoses, fuel filter and cleaned the fuel system. The fuel pump was replaced a little before I got it. 2000 miles later it is stalling again at any speed mostly when the rpms go up and on hills. We are trying to replace the map sensor but can not find it anywhere under the hood. Does this car even have a map sensor and if so where is it located... We are also trying to clean the throttle sensor but cant seem to get it out without taking a bunch of other pieces apart, is there a trick to this. Is there anything else it could be... We are currently stranded in IL and could use a bit of advice. Thanks a bunch...
