I actually have a 1988 mercades benz w/4.0 gas when I drive and the motor reaches operating temp the motor starts missing try to accelrate and it boggs down,when you let off the peddal motor will idle but won't accelarate sometimes it shuts off and sometimes it doesn't. The fuel pump and relay have already been changed I first thought that the cat was stopped up but it was gutted. What sensor or whats stopped up?
