Hello,
The check engine light has come on my 94 Navajo. Also, the engine is idling roughly, and occasionally misses at higher speeds (both started at the same time). I scanned the diagnostic codes and got the codes 157 and 158 (Mass air flow sensor voltage low/high), but I don't have a diagnostic procedure to check to see if the problem is the mass air flow sensor, or just a symptom of another problem. I have already checked for obviously cracked hoses and loose connectors, but everything "looks" ok. So the question, is this likely the mass airflow sensor, or are there other possibilities to check out before replacing the MAF? Thanks for the help.
