I cant read live data with the scanner i have. Its not just a code reader but it doesnt have that function. Either the temp sensor is bad or possibly a wiring issue im assuming?

Thats what i was thinking about the ops too. I will probably just toss a new one in and see what happens

 

The scanners at the parts stores around here will read live data. And it is something you can do right quick in the parking lot. (and if it's bad, you are right there to get a new one. )

Might give that a shot.

 

I will probably do that tomorrow and see what happens. So im looking at readings for the coolant sensor...and i should probably monitor the iac and tps too while im at it

 

Ok so my scanner does read live data. What am I looking for? What should all the readings be at? Thanks

 

At cold startup, Engine temp should be awfully close to ambient. As the engine warms, the reading should reflect that. See what ya get.

 

Ok heres what i got. I plugged the scanner in and went to live data. It read the ECT at 59 degrees without the engine running. Its 55 here now. I started it and the temp slowly went up. Also the TPS was at 11%and didnt move. The IAT was at 57.2 degrees MAP 12.1 the RPM were at 848m so where do I go from here? Oh also the the truck smells when running. Im wondering if its out of time and was like that before i took it apart. Let me know what you think

 

Oh and the spark advance at idle was 20-21 when i revved it it woukd drop all the way to 4 and then come back up

 

Did TPS do anything when you stepped on the gas?

 

No it didnt move. Stayed at 11. I was in park wasnt driving. I checked the MAP sensor it looks good the boot is ok. Im outside messing with it now. Its running. Kind of rough still and smells like its running rich as hell. Stinks oh and i think my temp gauge is shot it doesnt sweep when i did the test.

 

Also finally just got a code. Its been running for about 30 minutes and its a P1281. Engine too cold too long.
