Mr Grumpy, and all who read,
This is a long one so here we go.
Bought a sick 85 coupe, rods hammering and fuel system drowned in water. Got her for a song so I decided to rebuild, new everything, almost. Haveing never peaked under the hood of one of these things before, I stood across the shop, ran and took a swan dive into it.
Installed a rebuilt motor, 72 model 350 #2970010
Same heads 72 2.02/1.6 I think LT1
Everything new except rods, block, crank, and heads. All went to machine shop(used many times).
Got it all back together replacing all sensors and such along the way, fired her up like any other 350, got a couple of codes. Simple stuff, o2 senser, water sender and knock sensor backwards, stuff like that. Solved all of those, now I have no codes, but more problems! The thing wont idle down stays around 1000rpm, has a miss, and wont come to temp. So far, I have done all the setups and checks as per (grumpyvette). Now I bought the temp sender for the 72 heads because the 85 sender was too small, possibly wrong one?
When I drove it it would stumble off start and then surge forward still vastly underpowerd. Went over everything I know to check Timing,Cam gears,Fuel pressure(47),Compression,Valves,etc. Pulled the plugs all look dark like too much fuel except #7 Its shiny brand new! Now im at a total loss! I have a Snap on scan tool although I got it for the car so I really dont know how to use it. I checked everything I could, The computer goes open/closed, no codes, all the stuff seems to be working, at least I can see it working. Hit the gas IAC moves, TPS .56,o2 sensor changes, stuff like that.Any ideas where to even begin would be great! Thanks from Texas!
