Hey all

I just finished converting my 3.4 to a 5.7 , just completed the fun task of getting rid of airbag lights and ABS. anyway, Now i can concentrate on how the car is running, i suspect it is the optispark, and wires, or maybe injectors. Before i go through that ... i want to make sure i am not missing a piece . I was looking through my haynes manual and i found this picture, and it says it is for 97 and earlier LT1's. I normally would just accept the manual but since i have the 1993 things are usually different, also i cannot find a connector that would plug into this sensor.

any help on this would be appreciated, the car is just not running... right... It is prolly the optispark/injectors/wires. here goes another grand crap.


thanks all!

 

Lt1's are supposed to have maf sensors yes, I believe they are the same 1's that are in ls1's too.

 

If your engine is a 93 lt1 it runs by speed density, not maf (unless someone has tried to do the conversion, then thats a whole nuther mess).

 

If the engine is off a 1993 it is NOT run by a MAF, its off speed density.

 

Does your motor have a fuel rail cross over at the front of the intake manifold? If no, its a 93 and you dont need a maf...that is of course its been swapped over to the 94+ style intake manifold which isnt very likely.

 

Ok thanks guys! yes it is a 1993 engine, where do think i should go next on my quest to get rid of this rough idle.

 

check which codes are being thrown.....

 

the check engine light is not on, and there are no current codes. this is a great point, if the optispark / injectors/ wires were broken wouldent the computer know that and yell at me.
