I would inspect all the lines and look for any that are damaged or wearing out and replace them.

Thanks guys. I see that all of the vacuum hose have cracks in them. Do I need any lubrication to put the vacuum hose in?

Is there anything I should know before I replace them? It is easy to put them in myself right?

Just make a shopping list and go get them. Take samples of each size and get 50% more than you need. It'* cheap. High vacuum grease on each fitting will help, but not required. Replace every line you can, and be careful with the T fittings on the vacuum manifold mounted to your firewall between the maxifuxe relay center cover and WS wiper motor assembly. (That'* the most likely place for a leak, too).

They are very easy to put on but the ones that are in the picture above cant be replaced by regular vacuum hose because those are molded that way and arent just bent hoses. If you bend regular hose then it will pretty much close off the hole and would make things worse. You probably have to order those pieces from Pontiac or maybe an auto store has some of those too.

Or just plan on a larger radius.

Hey guys,
Since my mechanic said that it was my vacuum hose that works, I changed it but it is hard to start my car still and the check engine lights still comes on.

Do you guys know where I can get my car scanned for free?

Please put your year and model in your signature. It'll help alot.

You need to find a place that will scan for OBD1 with an OBD2 cable. Some auto parts stores will do it for free. Just call around.

I went to Sears and they said nothing was wrong. They also gave me the paper work that says it is ok. They just had to clean the corrosive on the batteries.

I think I will get a tune-up just incase. Thanks guys.
