1990 Volvo 740 Problems

Engine stalling/stumbling problems can be caused by a failing mass airflow sensor.

A faulty RPM sensor can cause the Check Engine Light to come on and cause a "No Start" condition.

Delayed and/or erratic shifting can be caused by the transmission kick-down cable sticking. Since the oil pan has to be removed to replace the cable, have the shop replace the transmission filter at the same time

could this be vac leaks or is it map,o2,sensor related? fuel pressure? also will occasionally buck while driving at interstate spd. there is no check engine light on also the speedo has become erratic and the anti lock light is coming on after hitting a bump and now stays on longer/more often

It just hit the 20000 mark could it be something in the drive shift, is it hard to change the bump stop.

I pulled the head and there is a hole burned through the top edge of the piston.
