ok first and foremost i didn't do this engine swap (if i did it would of ended up with a carb)so i don't know right off hand if it had 350 sensors swapped over with it other than ones i changed.injectors are from the 305. Engine is an l05 (i guess .i knowt its out of a truck )bored .30 over with 193 heads.stock exhaust manifolds stock intake and throttle body and maybe a mild cam can;t really tell because the egr valve problem i m having.i m assuming it has a 350 knock sensor since they go in the block itself afaik.

seems to run rich idling (black smoke)but lean under more throttle.i ve logged some drives to work and back with winaldl but i don't know how to read the output log . fuel injection is waaay over my head.Under error codes i get 22 low tps ,34 map low. and 42 electronic spark timing ,and 32 egr ( i know the egr valve is sticking )and maybe another one or 2 i can't recall atm.

the prom is the 305 prom.

i ve changed the iat sensor (was reading -400 c) ,put a 350 map sensor in and changed out tps.



i m not looking for anything high performance right now i just want to get this to be like it would ve been a stock 350 tbi in an fbody had gm made them like that.

i ve got 350 injectors for a 89 caprice 350 tbi that i havent installed yet because its running rich right now.

would a 350 tbi caprice prom and injectors fix my issues (after i take car of my egr sticking)?


sorry if this seems like a pure randomness i ve been up waay too late tonight.

 

no those would not fix your problems.

when you changed the map, tps. did those codes go away?

I am not really sure if I know where to go with this. But I do know a 305 prom and computer would run a 350 but is not optimal.

 

when i originally swapped the map and tps they stopped triggering the check engine light, now they show up under winaldl(i did unhook battery to clear stored codes after swaps).only thing that makes it flick on now is the egr sticking.
for what its worth my car does seem to bog down worse than usual when hooked up to my laptop.
