Thanks. But since the intake manifold is plastic. I just used a 1/4 drive with the 10mm socket and went 1/2 turn past snug. I am hoping that this will work. I had 5,6 cylinder bolts really loose. it was causing a P0171 error. It would also stahl out went the temp. was below 20 degrees. Started...

In the endless repair of the Po171 code. I am now replacing the intake manifold gaskets. Anybody know the torque settings for the bolts? and should lock tight be used?

Yeah, hard to believe. But all the readings from the sensor never changed with all that was replaced. I cleared the codes with every repair and parts replacement. The vehicle is running really good since tuesday morning. No old codes and no new ones, checked all the sensor via diagnostic tool...

Lucky man, or should I say Owner

I had the same problem with our TB, It ended up being a dirty throttle body. Make sure it is really clean and the vacuum choke passage way is clear. Also what are the readings from the Mass Air Flo sensor? has this been cleaned?

The issue was actually a dirty Throttle Body. performed a really good cleaning of it and the truck is running great.

I think that Roadie may be onto something. I looked at the Intake PSI and it is all over the palce and then it goes straightlined, for a couple seconds. then it starts to go crazy again. I take it that it should remain relatively stable? correct?

I just looked the the in-take manifold. what a pain in the ass. and that is just looking at it. But I will snoop around some more. :crazy:

Hi roadie, I can send you the recording of the sensors, I took the recording when I was having the problem. O2 sensor is fluxuating working normally. I think I need to make some more checks on some of these items and get back to you. Thanks

I changed the o2 sensor because the nuckleheads at Auto zone said it was the problem. Then when that did not fix it I purchase a OBDlink SX diognostic reader. I also picked up a spare coil pack from a parts store. the check that i made on the coild was ohm readings on the coils and visual...

Hello, Have tried the cleaner, no difference. I truly think that the electronics or sensor is causing the fuel to lean out too fast and causing the rough idle or stalling till the motor or outside temp is warm.

Hello Guys, Got a good one. we own a 2006 TB 4.2L with 145,000 miles. The vehicle has given out coeds of p0300 and p0171. I started by changing the Oxygen sensor on the first bank. The rsults never changed. When it is cold outside <32F the engine will start right up and idle at 1200. after a...
