IT GOES ON TO THE DISTRIBUTOR as its for the vacuum advance so when you put the throttle down for power the plate inside is turned around 1/4'"there for advancing the spark ,so it dosent backfire through the aircleaner,
So on the side of the distributor theres a metal diaphram and it should have a small pipe on it and thats were it goes..
Have a goodday Let me know if you need any more info. RON

1999 Chevy Blazer backfires inside the engine and blows off a vacuum line on the intake manifold.


in order for the engine to pop back in the intake it has to be firing when an intake valve is open.The best place to start would probably be the distributor cap replacement.the toughest part of this job is the smal torx bit screws on the cap and not breaking the distributor. the screws were threadlocked ,and the distributor is made of plastic.be careful not to over tighten.

Sounds like you have a fuel leak inside the intake. Remove the upper intake manifold. Cycle the key on and off and check for leaks from the fuel lines and pressure regulator.

1997 Chevy Cavalier is backfiring and sputtering sometimes on take off or acceleration. Any ideas what the problem is? New fuel regulator, all new injectors, done alot to this car.


Here is a list of some things that can cause it,
Emmissions system not functioning properly,
Faulty secondary ignition system
Fuel injection system in need of adjustment
Vaccum leak at fuel injectors, around intake manifold, or vaccum hoses
Clogged fuel filter
Weak fuel pump
To test for a vaccum leak, get a can of starting fluid, with the engine running, spray around the intake manifold, the vaccum hoses, connections and fittings, where ever you spray and the engine rev's up a little, you found a leak.

I have a 1993 chevy blazer 4.3. We replaced the fuel filter and fuel pump. When I start it up it starts okay. Once I drive it and let it sit for about 30 minutes or so it takes a couple of times before it...


Is it a vortec engine if it is your fuel injector may be the problem. Chevy ran one injector on the vortech engine it is under the upper intake manifold, it has 6 plastic hoses running to each cylinder under the manifold. if one of these hoses are leaking its dumping raw fuel into the manifold during hot soak. that fuel is getting picked up by intake air when trying to start. and flooding it out hence hard to start. gasoline evaporates rather quick so what fuel was in the manifold when you park for the night has evaporated by the next morning so no raw fuel for intake air to pick up easy start. Seen this problem many times. pretty easy fix but a bit pricey around $200

Where is the IAC on a 2000 Chevy Blazer


On the intake manifold ( top of engine ) near air throttle body ( like where a carburator would be ) pressed against throttle linkage. Hope this helps.

Engine pulsates during idle and from second to third gear


Try checking for vaccum leaks, use carb cleaner and spray it around the base of carb, vaccum hoses, edges of intake manifold, take pliers and squeeze the big line to brake power booster & see if it changes, pull the pcv valve out and cover with your finger see if it changes idle.
