GM TBI Engine Idles High

If you’ve been to this site before, you might be familiar with my 1991 Chevrolet C1500 project truck. Long story short, I needed to swap the V6 in the truck for another engine (it had a rod knock). I got another 4.3L TBI V6 from a salvage yard. I recently got to the point of starting the new engine up, and it would idle at 2,000 RPM for 30 seconds or so and then drop to 1200 RPM.

Chevrolet C/K 1500 Centurion Conversion

Mentions of production numbers Good luck finding a Centurion on the “cheap”. They only made like 27 per year, from what I’ve been told. From what I’ve been able to gather so far, it is most likely one of about 30 or so crew cab 1500’s in this body style, and one of only 3-4 from 1998 the last year of this body style. From what I’ve found they only did about four a year in 4wd and only a dozen or so in the 2wd models.

Removing Paint from Vehicle Windows

I bought a camper shell for the 1990 Chevrolet K2500 and it’s great except for one thing: the previous owner painted the windows black on the inside. This looks cool (as much as a shell can) from the outside and is perfect for sleeping in. It looks like the darkest tint you can get and is nearly pitch black when you spend the night in it. However, you can’t see at all when trying to back up.

Rebuilding a GM 4.3 Liter V6 Part 1

As I talked about in my previous post, The The New Project: 1991 C1500, I need to rebuild the engine in the truck I recently bought. It’s a 4.3 liter V6 with TBI. I’ve been interested in learning to rebuild an engine since I bought my 1990 K2500, but I did a little research first to make sure I wanted to take on the task. Should I rebuild? There are few options when it comes to reviving a vehicle with a worn out or destroyed engine.

Installing Headliner Insulation in a Truck

It’s getting hot here in July and my 1990 Chevy truck’s AC hasn’t been converted to R134a refrigerant yet. And it’s out of refrigerant. So I’m noticing all the ways in which the interior gets heated up. The other day I was sitting in the sun waiting for someone and I realized heat was radiating off the inside of the truck’s roof. The front part was cool to the touch because it is double-layered metal, but the back part was another story.

New Seats in the 1990 Chevy Truck

I finally got some “new” seats. These came out of a salvaged 1994 Chevy truck, but they were originally from a 1990 model. Either year would have fit. It took me about 6 months of watching and waiting to find some decent condition, blue seats for the truck. Before installing the seats, I thoroughly cleaned them with Shout Auto Dirt and Stain Remover (you can get it on Amazon here).
