Smart (and great) idea on the subframe stand Mark. Will make it a bunch easier to work on.

 its just too bad all your nice work will get covered up

Even though stuff like this gets covered up, it's the overall feeling and satisfaction you get knowing that you've gone through in detail in these minor systems. It makes my entire classic car experience even better, the car seems to just feel better. If I never had these things to do, I'd probably not even bother having the old cars.

What I did in the garage today....

I reminded myself why I'm anti-LS engines!

Our 2008 Impala 5.3 developed a miss on Christmas Eve while we were plowing some snow on a pretty bad road on the way to Grandma's. Engine light on, engine runs like crap, at idle your eyes burn if you stand outside the car the raw fuel smell is so bad. Took it to Winnipeg yesterday and it was running the same but under 25% throttle it misses,  anything from about 25% - 100% throttle it runs great. Go figure. BUT it's sucking gas like a pig, trans is shifting super hard etc. All due to the engine light being on I surmised.

Today my friend came over with his scan tool. P0205 and P0300 codes, the P0205 code being miss on #5 and I think the P0300 said due to injector wiring issues.

Called the service manager at the dealership where I worked so long and said "this is one of those calls where I want free advice and need you to fix my car over the phone"! (He and I worked together for about 40 years at 2 different dealerships before I retired in 2020). He asked a few questions and then said "swap the coils between #5 and another cylinder".

I took it one step further and swapped the coil, plug wire and plug between #5 to #3.

Road test. Works perfect. Great.................... I didn't change anything, didn't find a problem and now it runs and scans perfect. Arggggggh.

Maybe a bad connection at the coil or injector? I wiggled the injector wires at the same time I swapped the parts.

Give me a carb and points any time.

 Not to Diss you Carl..but you luv carb and points because you know carb and points. Once you get to know and be able to circumnavigate around the LS....you'll luv them! These engines are all bout grounds!! 5 v sensors so any resistance can muck things up! ..........and you fixed it for 0 $$$$...  O ya.....plowing snow with an 08 Impala = driver abuse..........

If I were to do it all again, I'd definitely do an LS. So much to learn and tinker with in the program.

That is one of the Diagnostics on Newer cars is to move coil and plug to different cylinder, But move the parts to different cylinders then you can 

verify part by which cylinder it moved to. P0300 is generic misfire code and P0305 should have been cyl 5 misfire. Not sure about P0205 code. Unless GM has there own 

numbers for misfire.

 I checked P0205 and it is an injector circuit issue. 

Put about 40 miles on the car today, still perfect with the work I did. I'm guessing it might have been a bad connection. I fully expect it to return, I'm just curious to see if it will return on #3 or #5.

What is the weight difference between a big block old school and an LS engine?

 Just guessing but I'm betting a big block would be 125 -150 more?

 Depends...some LS are aluminum block. Looks like 375lb for alum LS long block and 675 for a BB long block. Maybe add 100 lb for a cast LS

Hunkered down inside today while the winds howl and the snow comes down. However yesterday was a nice day. I was able to obtain quite a few 8 foot juniper 6x6's milled nearby for a song. I have no idea what I will use them for but the price was too good to turn down. Ol' Sally had no problem hauling them. It took two truckloads to get them home. I stacked them up on the south side of the barn for now.
