Hi this is my first post in etcg Im 16 and I have recently completed my first engine swap on a car. Its a 1994 regal with the 3800, Its my dads car, we have had it for 2 years we bought it with 18000 miles on it for the estate of and old lady that had passed, so long story short The car ran beautifully,We had put in a new battery and alternator and it ram like a new car. So my dad had it on a trip when 800 miles from home the oil pan gasket went and of course he drove it until the bearings went. So he got a price of 2000 dollars to put a salvage engine in it which is more than my family paid for the car. Being that between me and my dad we have a pretty good selection of tools I decided to conquer the job myself. So with the purchase of an engine hoist and a salvage engine with 60k on it that was made 11 days apart from the engine in the car I was on my way. It took me 2 weeks after school but I watched a lot of erics videos and did a good bit of research, I documented every step I took and took pictures along the way even though I have one of those minds that just seems to remember ho things go back together. So the car ran fine even with the bad bearings had plenty of power and could burn the tires no problem. So with this salvage engine I basically stripped it of all its components (wiring, sensors, hoses, replaced every gasket except for head, and intake gasket, I lubricated every cylinder with some tranny fluid, new plugs, wires, all the sensors are either from the old engine or are new, The throttle body was from the engine with the bad bearings, etc. the car just doesnt have the power it used to have now, there are no lights on, it starts right up there is just this hesitation/miss/sluggish running.i have checked everything that I have thought to check and honestly dont know what else it could be. The one odd thing is that the lower rad hose doesnt get hot not even really warm, I am pretty sure that I have bleed it properly with the bleeder valve/ rad cap, the thermostat is new and I did check it in boiling water, the car doesnt overheat but it does run a little warmer than the car used to ( it runs at like 220)which is the middle line but the temp never even used to get to there ever. It has the 4 pin obd adapter which I dont know how to pull codes with but there are no lights on, Im really at a dead end on this one, someone please help, sorry for how long it is, I really appreciate any help, and stay dirty as always, Thanks!

Thanks for all the help everyone, a couple days ago I checked all of the motor mounts, flex plate to torque converter, and pretty much checked over all of my work, I am pretty sure Its on of the sensors on the throttle body, I think the TCS sensor? anyhow I am taking it to a mechanic that my dad knows thats A GM tech. I will let you all know what the problem was, Thanks!
By the way I looked at that page about the codes, and its weird because that still isn’t the connector I have, it looks like a regular obd adapter but it only has 4 terminals in it, I will try to post a pic, Plus I had to start working on my 05 Durango because that car is more important to me, the Buick is just a secondary car really,Thanks Again!
You may not be looking at the correct connector, GM has been using their connector since the late 70’s. Keep us posted on what they find.
So I dropped the car off at the shop earlier this week, They started working on it yesterday, havent heard from them yet, its funny though, the day before I took it I checked over everything, the only thing I found was a burnt out fuse for ENG EMIS just a 15 amp fuse, I changed it and the check engine light went off, the car still ran the same though. The car sat overnight and when I started it to drive it to the shop it ran real rough, then it seemed to correct itself on the drive over. It all of the sudden ran really good I still took it in to make sure that was the only problem plus it needed to be inspected, new tires, and the turn signals were acting goofy, I think it is just the switch and not the wiring harness because I have heard that they go bad? I will post back and let you know if thats all it was. Thanks Everyone, And great video today Eric!
