If any one has a pic from an '85 TPI car I'd appreciate it as well as the Vehicle Emission Control Information label as my car doesn't have them. I tried to get them at my local Pontiac dealer but they said they couldn't get them anymore.

My wife has a 84' Pontiac 6000 (amazing good shape body and all), but I had to replace valve cover gaskets and you talk about a NIGHTMARE. I had to track down a vacuum leak on it once and sometimes I felt like ripping the CCC out and putting a holley on, but eventually managed. Graphics like above definitely help out. Great Job 57!

Do any of the diagrams tell you what size vacuum tubing needs to be used? Looking at mine it doesn't look like a standard size or would it really not matter?

[Apeiron]

As long as it fits the ports.

[confucius101]

do you have any nice large shot's like that of the 91 3.1 setup?

I need to know (preferably a picture) in detail where the "TO HVAC" goes exactly. I'm thinking this might be why I can only get air to come out of the defroster vents no matter what I have it set on.

Guys I just bought a 91 Camaro Z28 Convertible, it had a 305 TBI. I did away with it and I installed a TPI system from a 1989 IROZ with a Mass Air Flow Sensor . I kept the original 1991 vent canister wich has a different diagam. My question is, should I set the vacuum lines up as the TPI 90-92 or should i find the vent canister for a 86-89 TPI?????

[piercesteve2000]

ive got an 86 305, berlinetta. the vacuum diagram has lettering on the carburetor. how do i identify which of these letters represent the vacuum on my carb, i know of at least one that is above the other. the diagram just shows a left to right and such.

[blue68nova]

I am repair my 1982 z28 that has a crossfire injection system. I can not find the EGV vacuum control solenoid anywhere. Does some body know where i can get one of these? Deal is telling me that they no longer make them and will be very hard to find.

[z28crazy]

Do you a version of this diagram for cars without emissions equipment or more specific with the the airpump and stock air cleaner removed?

Also can anyone tell me the name of the sensor that is near the thermostat and has two vaccum lines attached to it?

[schilke05]

I need help. Can somebody please show me a vacumm diagram for a 1982 camaro with a V8 305 CROSSFIRE. Cross fire is the key.

[breamrules]

A vaccuum diagram for an '89 Formula (5.7) with TPI would be outstanding.

I recently bought my son a 1983 berlinetta with the 2.8. It ran like crap, so I started with the fuel filter, cap and rotor, plugs etc..... you know the typical stuff, and it didn't get any better. It's carberated and if I hold my hand over the carb it runs better..... any suggestions???
