I have had a cel on for a while now. I pulled it yesterday and it gave me p01345 which is something like Crankshaft position sensor / Camshaft position sensor correlation. I did a little searching online and found some gm truck guys talking about the gear on the distributor wearing, timing being, or timing chain stretching. I only have about 30k or so miles on this engine, so i guess its not the timing chain. When i did the OBDII swap, I couldn't afford a real good distributor so i went with a cheap one. I'm not sure if this has something to do with it, or something with the cam sensor. Does anyone have any info onthis? It's a 92 camaro with a 350 tpi and was switched to OBDII. It also runs like crap and misses at low speeds especially when cold, but smooths out a little when it warms up. It also gave me a temp sensor code, which i assume is why one of my fans wont turn on now, but i don't think this is related

 

So seeing that no TPI engines were OBD2 , what computer / harness / dist are you running now ?????

OBD2 only came on 96/97 LT1 cars with Optispark dist

 

i did the obdII conversion from these boards. It has a dizzy from an 01 express van, computer from an 02 LS1 4th gen (also ran all of the trucks from 02-04 but i cant remember the part number right now) and a harness from efi connection specifically for these cars and an obdII conversion.

I'm pretty sure it did not have this light on when i originally did the conversion, but it has been on for a while now.
