The check engine light came up on my 98gt and it threw two codes- p1131 and p1260, where would i go to find out what these mean.
|
Autozone.

|
ok thanks alot
|
I clear the codes, and a few days later the same code came up again(Lack of Upstream Heated Oxygen Sensor Switch - Sensor Indicates Lean - Bank No. 1) but from another o2 sensor. The car seems to run fine does this mean i need new o2 sensors, or a whole new tune since it says im running lean?
|
well. if u wanna check if u are really running lean then you should put it on a dyno and check the A/F ratio. do you have an aftermarket midpipe? if u do that could be causeing the SES light
|
Whats done to the car?
|
I bought the car used with a catback and I think it has hi flow mid pipes because it only has 2 converters. Other then that I did a pi swap and have a 160 thermostat. I've been driving the car since the begining of september with the swap.
|
Full PI swap? Get it tuned.
|
i got a tune from mustang tuning when i bought the sct
|
when i ordered the tune i had included everthing done to the car even the pi swap. Do you think its still the tune and i should have it dyno tested?
|
still get it dyno tuned! even if they tuned for the heads its only enough to hold off a dyno tune for a short time. Nothing beats a dyno tune cuz then you can get the A/Fs at the perfect numbers(unlike mail orders which can have the car run lean or rich). oh the other plus for the dyno tune is you can see your numbers then.
|
sounds good ill go with that then thanks
