Thread: What's this issue?

Not trying to be a dick, but you are glossing over the painfully obvious first code: MAF circuit malfunction.

As I said, you probably fried your MAF in your wiring adventures and once it fails, the system immediately goes to full rich.

Also
1) If you are not a 97-98-99 SE-R/SE-L, you do not have a IAT sensor
2) Code one and two are probably related.

Ad looking at it now, these codes are all OBD-2 related (sans the MAF ofcourse). What ecu are you running??

I CANNOT keep track of all your setup..........gives me a headache

yea, I am thinking that I may have wired the maf wrong and messed something up in the process..so I will be looking for one of those as well as a pigtail so I can get the right wiring together unless someone knows the pins on the maf as well as the proper wire colors..car is basically a stock 96 se-r everything (motor and ecu) but in a 98 sentra shell

All I gotta say is think about your setup before throwing a bunch of money at it. It seems you just threw parts on it that seemed "correct" and continued on your way (which is probably the reason why a majority of the people you tagged did not respond to this post)

MAF: Reads airflow coming into the engine (if this is fubared, then everything after the MAF will be incorrect, INCLUDING the requirements of the injectors and fuel demad)
O2: Reads oxygen content of EXHAUST after it has exited the engine/cylinders

Stock MAF for the B14 chassis is the same across the board as well.

Good luck!

well I tagged jet because I bought the car from him to see if he knew anything about the exact parts that were in it..and pete because I bought the motor from him, and then just the top shoutbox offenders haha

but I am going to try and find me a good b14 maf and pigtail and get the wires in there correctly and get the car running better and assess remaining codes from there..im thinking that getting a good maf in there and wired correctly will correct at least the 2 codes and then ill go from there..sorry for all the excess information..i tend to ramble a bit

To the contrary, a majority of your posts were actually lacking the necessary information as no one could figure out what injectors, MAF or ECU you were running

wellllllll my original post actually just had a progression of different setups and I thought that it said in there what exactly was in the car before I started describing the symptoms
