Hey guys, I was driving today and all of a sudden my 91 ls started sputtering and dieseling. If I nail the gas it does it and then it goes away at high rpm.It idles rough as well. It died once but I started it back up and it continued to run. i just pulled the codes and this is what it read. 13,24,31. Could someone please tel me what they mean? thanks Michael

I just started up my car and I unplugged the mass airflow sensor and the idling characteristics performed a little better. When I pluged the sensor plug back in the rough idle came in immediately. I am really thinking the mass airflow meter is junk. I was reading some books at work(autozone) and it states that some vehicles intergrade the intake air temp sensor in the mass airflow meter as well.

Michael,

My dealership wanted 1100$ for a new sensor + labor. I found a used one for 225$ on-line and did it myself.

Ok I finally fixed my car after running around all day and trying to work my regular job. I found a mass air flow meter here in phoenix for $175. I put it on and still the same problems. i looked down by the powersteering pump and "BAM" 2 wires(white and red) was starring me right oin the face cut. I pulled half of my car apart on the passanger side to see where the wires went. low and behold, it was the cam position sensor. I mad my manager drive to the lexus dealer and by me another one. I got a 20% discount on the part, so it ended up costing me $111.00. I put that part on and she now purs like new again;)So I ended up spending about $300 today that I didnt need to spend. that money was going into my speed boat :( the only good thing is that my laxbaby is well again;) Thank you for the help guys;)

Michael
