I was looking for some advice.....Recently did a plenum gasket and pan change with the hughes kit. While I was in there I figured I would put in a hypertech powerstat since I have the programmer. Now, every once in a while, I getthis code. I know what the code is, I was just wondering if I'm the only one with this problem using the powerstat. I put some cardboard over a section of the radiator and that helps most of the time, but it still comes on every so often. I think the powerstat is a 180 degree unit, but I'm not sure. Maybe I should just put a stock 190 degree back in it.....any thoughts?

 

I got that code at the beginning of the winter. I put a section of cardboard over the center of the radiator that blocks off about 2/3 of it. It has gotten down to about 15 here since I did that - and I have never had the code come up again. It doesn't get hot either. Stick with your 180......

 

Thank you Racinfan....I'm just glad I'm not the only onewho hadthis problem.

 

had the same problem and never thought to use cardboard. i just pulled it out.
check to make sure that its not stuck open. that could also be your problem.

 

I was thinking that too....but it doesn't do it all the time with or without the cardboard. I thought if the thermostat was stuck it wouldthrow that code after 20 minutes every time I clearit.

 

I got the same cod ethe other day at is was 95 here. I am confused about it. I went to autozone and the put a code reader on my Durango and it read: P1281 Manufacturer Control Fuel Air Metering. The manager at AutoZone said it might be a vacum leak somwhere. But looking at this site I am confused. The code here says it is running cold. I have also been advised on these forums to clean my Throttle Body and the Air Charge Sensor orMAP sensor as a cheap way to try to track down the problem. I am doing this next week. (could not hurt) I cleared the code and it has not come back on again. Maybe it was a fluke?

 

Aren't 180 stats great! Everybody is getting more power and better gas mileage!
But not me. I had to take mine out because the CEL kept coming on [:@]. Iwent back to the 195and no difference in power but gas mileage is better.

 

OK, I'm done with my workout. I didn't need any Redbull before my workout since I waswound up about changing back to a 195 stat![sm=icon_rofl.gif]
Anyway, to offer some help you could try another 180 and hope it runs slightly hotter and/or try another temp sensor. It wasn't worthmy time to experiment. My stat/temp sensor combination waslow by 2 degrees. So close, but no cigar.[sm=boohoo.gif][sm=signs003.gif]
