1987 Volvo 240 running too rich
My daughters 1987 volvo 240 is running too rich and did not pass emmissions inspection today. The car had sat for a while prior to her purchasing it. She also has complained of poor gas milage. I would appreciate any input of wjhere I should start looking for the source. the car starts fine and seems to run good, no problem idling, but has arough spot when decelerating.

It is a good idea to buy a Haynes Manual....The code tester should be on the left side (sitting in car) under the hood just behind the wheel well...little black box...the top comes off and there is a test led on the side of it..put the test led in the #2 hole press the botton...a light should come on...release the button and then a sieres of blinks will happen... 1-1-1 means no codes..the our codes are in the book and I dont have mine handy...good luck

The 1987 model doesnt have that so you cant check for codes. U have to check manually getting voltage reader and check the voltage coming from the mass flow sensor and the O2 sensor *** well.. Don't know the voltage the sensors get but i will try and and find the specific voltage u have to get.. But you can allways start by doing a tune up, like: spark plugs and wires, cap and rotor, air and fuel filter change, cleaning the throttle, throw a bottle of injector cleaner.
