I plan on getting a temperature gun and looking at the cat, however in my dinky little down they don’t seem to exist although I know my old agriculture teacher has one so maybe ill to talk to him.

Today I decided to use my scan gauge two that gives Map sensor readings and if I’m not mistaking map is the opposite of a vaacuum test like in Eric’s video about using a vacuum gauge to find a plugged exhaust. But the map readings should work in fairly the same way right?

I got 3.4 at idle and abut 4.5 when revved to 2000 rpm but I have also seen it like up in 11 area but I didn’t take note of when. Now I’m trying to figure out what those numbers mean.

Yeah I’m mostly curious as to whether its hurting my mpg or not

I looked for intake leaks and found none. But my mileage/misfires were Getting worse alot with the noise coming from the distributor cap.( sounded like it was actually hitting the posts) so I replaces the shaft with a replacement one from nappa and used my cousins computer to finish the timing. The motor runs alot smoother and seems alot quieter now along with my mileage seems to be about .5 mpg better then it was befor. 🙂

Today I noticed my o2 sensor wire was hanging down under my truck ( it had fell down fairly often since i got the truck) and while I was under there I decided to beat on my catalytic converters and see if there were any loose chunks in in them. And in one there is just what sounds like little pieces rattling around and the other one sounds solid as far as pieces rattling. I don’t think the o2 sensors have ever been replaced nor the cats. But I also don’t have any codes for It and the truck seems to run fine.

There is now emissions testing or anything here.

Also I resolved the gas smell in my exhaust it was the distributor shaft causing a missfire sometimes. The motor runs tons better now and seems alot quieter.

Well the missfire isn’t on any one specific cylinder and the computer only comes up with it once in a while. That is a good test though I think I might try it. Also the exhaust looks pretty normal and I’m not losing coolant but once in a while the exhaust smells a little like gas and it usually corresponds with the po300 code

Hey thanks those were a lot of help I actually figured out that it was the switch not transferring power to flip the relay I changed the switch and it fixed the problem! Thanks for the help.

Yes it has acdelco plugs, I’m not going to hot rod it or anything I just use it for getting around. I’m looking at a a1 cardone one that’s new it’s supposed to be oem but its kinda cheap and I’m skeptical about it. Also I think I would probably just go with a new coil to while I’m at it the truck has 215000 miles on it and the shaft and coil are probably original. Are the 45000 volt ones any good or would I just be better sticking with replacement parts?

It is the 5.7 vortec would I be ok to put the distributor in then drive three miles into town and have a shop do the computer part?
