Question about 2000 Chevrolet Blazer

1 Answer

High idle air intake gasket I have a 95 chevy blazer with a 4.3 litre engine. It has a high idle. It runs at 1200 when starting in the morning and around 1700 when engine is warm. Today i totally blocked the air intake and it didn't stall the engine, which i think it should do. Then i used a propane torch and open it without lighting it, i held it were the air intake cover meets the engine, and then the engine speed went up. Does this mean i've a leak in the gasket and need to replace it? Thanks

    Spraying brake cleaner around the intake gasket increased the RPM on my engine, and when i took it apart i noticed that the gasket was broken. I installed a new one and the engine runs like it supposed too. Thanks

I have a 2002 chevy blazer 4wd 4.3l I overheated the engine and blew an intake gasket replaced it but now it shifts at high rpm and idle when started is around 1100 but when I put it in park after I drive...


On over heating an engine there are several items that tend to warp from the heat. The intake manifold required a new gasket so a good place to start would be checking for a vacuum leak in this area as it will alter the idle rpm from incorrect air/fuel ratio mix. Run fault codes to see if any sensors were affected by the over heating engine.

Idles high then dies, new fuel pump and ecm


I would start with the vac leak idea.
And is the check engine light on when it is running ?
If so you should have the computer checked for trouble codes first.
There has to be a source for extra air coming into the intake or throttle body for the engine to run fast at idle, assuming the idle air control valve is working correctly.
That air source has to be found and fixed first.
It could even be the throttle plate not closing completely.

95 ford probe want idle after warming up


when cold idle is going, listen to intake manifold with hood open. This will involve getting real close to the intake side of the engine. If you hear a whistle or air draw from anywhere around the intake, there is an air leak to the engine. The intake manifold gasket maybe cracked allowing air to bypass the intake sensors at cold when the gasket is closed. But when it warms up, the gasket allows air to bypass the intake and causes a stumble, pause at partial throttle or a wondering idle. If you increase the idle speed, it confuses the cpu and causes the engine to run eratic.

I had an 89 Chevy Silverado with a high idle problem, A lot of money later and a lawsuit against a repair shop that said they fixed it and they didn't caused early engine failure and they wind up paying for a new engine. Long story short, I found out the main cause was I had to replace the throttle body gasket because it was bad causing more air intake and the on board computer tried to compensate for the air by adding more fuel therefore, high idle. I hope this helped.

What are signs of of bad intake gauset on a 99 chevy blazer


depends on whether its leaking coolant or air, since both run through intake. if leaking coolant, you will see coolant leaking from either the front or rear of the intake itself. it can also leak into the engine, causing coolant to mix with the oil. if its leaking air, usually a small leak will present more when the engine is cold, with rough running or high idle. a large leak will run rough all the time, but should be able to hear air hissing if large enough. a vacuum leak from the intake will sometimes present as a check engine light, with codes p0171 and/or p0172, depending on whether the leak is on one side or both.

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
