1991 Volvo 740 4 cyl Two Wheel Drive Automatic 186000 miles
Let me start by saying I have replaced the following, RPM sensor, coil, rotor, cap, K1 fuel pump relay, Ignhition switch and radio suppression reays(both of them). After taking it home $$ I replaced the radio relays and ignition switch. The problem with the car is it will run anywhere from 1-25 minuetes and then it dies. I was able to check and verify the spark is missing at the point it dies. After a nfew min it will start to spark again and actually start on the 3 cyllindars left connected. I am at witts end, I really like the car and hate to send it to the scraper. Thanks alot for the help.
