1991 3.8 liter engines used a Mass Air Flow sensor in the intake tract (measures incoming air) instead of a MAP sensor. The MAF sensor is located on the engine just behind where intake hose is attached.

check your cam position sensor and the electrical connector first. you may have a bad sensor. if the sensor is good, then the timing cover has to come off. if the timing cover has to removed be sure to change the seals, timing belt and timing belt tensioner while the cover is off so you won't have to re-visit the same area later.

Congested catalayic convertor will pose this problem. Less expensive problems could be oxygen sensor, or if your vehicle is equiped a catalayic sensor.

The warning lights started going on and off, all the gauges started going crazy. Then engine lost power and died. Towed it, put it on the charger and it started but would not stay running. One person said...


Most likely the alternator........ map sensor failure would bring up a check engine light and code not the crazy gauges and lights
hope this helps...Good Luck!
