Reading Datalogs on my 89' GTA
So I've had a ongoing issue with a misfire most noticeable at idle and a vibration after around 4500 rpms (I assume is a misfire also). The car is an 89' Trans Am GTA, the engine is a stock replacement 350 TPI, supposedly its .040 over, has a comp xr269hr cam, 21lb accel injectors, aftermarket fuel pressure regulator, accel runners, edelbrock high flo base, underdrive pulleys, and it was supposedly had a chip burnt by TPI chips. I'm new to Winaldl but from what I can tell is the car is way lean, especially below 2000 rpm and leans out again at around 4800. If someone could read these and give their opinions, etc I'd appreciate it! Thanks

You should try using tuner pro rt. Much easier to see the data.
