1995 grand Cherokee codes
I have a 95 grand cherokee with codes 13, 34, and 52, do I need to replace the MAP sensor(code13). Is code 34 due to a vacuum leak or do I need to replace the speed control. and is the O2 sensor bad or do I need to fix the mixture because it is running rich (code53). Please help with advise.

Welcome to CF.
The map sensor could be causing the other codes. Check the vacuum lines going to the sensor for any cracks or damage. Also check the wiring for any breaks.
While you're at it, check all the vacuum lines for leaks/damage. With the engine idling, spray fuel injection cleaner on the vacuum lines to find any leaks. An increase in idle speed will pinpoint any leaks.
