Where should I strart off ?
I know it is SAI releated

 

start with a fuel pressure test...and regulator test...

then get back with us


and what does sai have to do with it??? sai is suspension and alignment related

 

Are you sure P0148 is the correct code?

 

Well that is what it says! in HyperTech Scan Tool
Funny After work home drive where my car was getting cooked
It didn't turn AirPump on and I didn't get message
Let see what it does in morning where it is little bit cooler!
SAI=Secondry Air Injection

 

Drop by AutoZone. They will scan it for you and tell you what the code is.

 

...well maybe there is no AutoZone in Canada, but there must be some store/shop that will do it for free. Do you also have a hyper crap programer.

 

The reason I asked if that's the correct code is it's not listed in my OBDII book, nor is it listed on the GM site.

yea

 

Unless you have an A-4, you might as well sell both the programmer and the scanner and treat yourself to a nice mail order tune. JMHO

 

It is already Program by PCM for Less
HyperTech is for Scan Tool!

 

Well then, you probably should do as suggested and chech your fuel pressure and make sure you are not running to lean before you really booger things up. Might consider changing fuel filter etc----anything that might be restricting your fuel flow. JMHO

 

That code is not on Shoebox's LT1 list, not on the GM service site for the OBD-II LT1. The air injection system codes are P0410 and P0412. The OBD-II standards dictate that P0148 is for "Fuel Delivery Error", but in 10 years of working on these cars, I've never seen that code listed as applicable to the LT1.
