I have a 1995 chevy lumina 3.1 and upon starting the engine will either hesitate and die or it will idle and when i press the accelerator it hesitates and then the engine dies...what could this be?


you need a tune up...plugs, possible wires too, they might have a lot of carbon tracking deposits on them ...clean (IAC) sensor, if you"ve never cleaned it, believe me it"ll be dirty.. and then make sure you completely clean you throttle body too inside and out! but wait an hour after before starting to let it air dry...clean air filter or replace it, and replace fuel filter if it hasn"t been replace in a long time. also after you"ve done this purchase a can of Sea Foam fuel system cleaner $10 and pour 1/2 can into 1/2 tank of gas and drive around even if its running "a little rough", for about 30 minutes and this should clean out any fuel injectors that may be possibly clogged up! if you you cant drive the car but will idle only after cleaning (idle air control), pour some seafoam in the tank and let it idle for about ten minutes then try to see if it will run. If none of this works then you probably have a fuel pump not putting out the correct pressure!

I am having trouble setting the timing on a 262(4.3l)chevy vortec engine 1995


You have to put the Ignition Control (IC) system in the bypass mode by disconnecting the "set timing" connector. This is a single wire sealed connector that has a tan with black striped lead. The location of the "set timing" connector with a Powertrain Control Module (PCM) controller is near the PCM connectors in the passenger compartment. Unplug connector (tan/black stripe) start engine set timing to 0 TDC, TURN OFF ENGINE, re-connect timing connector

1993 Chevy S10 Blazer engine hesitation with smoke from exhaust


Had a 94 Olds Bravada that did a similar thing and it was EGR valve on the front of the intake. It' s easy to take off and clean with WD 40 and if you have an air compressor blow it out good.

I have a 1995 chevy geo tracker that goes alright after 2 rpm on flat land but going up hill loses a lot of power .When sitting still i will press the gas and it will go to 2 rpm and then die down to 1 and...


What your reffering to is 1=1000rpm, 2=2000rpm, etc.

Sounds like you are losing power due to possibly wear on the engine; being a 1995 model, I bet it has lots of miles on it.

Your motor is probably just wore out and needs replaced or rebuilt.

Problem bad hesitation when cold


You should change all 4 O2 sensors, it will run better :)

Also check your compression. Not enough compression on any one cylinder will cause oil blow-by and cause it to fail emissions. Also, the EGR valve can cause the same symptoms.

96 4.3L Vortec S-10 Blazer died while driving


I am tired of people getting the run around on these engines, and the "Like." This post will be repeatedly posted threw out the world wide web until It ranks number 1 in the google search list when a user googles 4.3 dies, or rough idles etc... For me, "There is absolutely No information on this when the problem occurred for me!." For example, We would not search for "the year the valve covers changed on vortecs" when we keep getting thin ones from a vortec thrown at use. As the Idiots "Humans" we are we would simply search for , "Flat valve cover gasket." In return we would get nowhere.

After we learn the problem, "After" we can then properly search google for the solution. For example the proper term would be, "What year did the vortec valve covers change in?" Walaa. Before hand we was googling for "Flat vortec gaskets."

My point, "You can not google for a solution if you have not already solved the problem."

CHEVY DIES at stop sighns, red lights,Redlights etc. If you are here reading this, Then it is because you have wound up here due to your engine stalling or not starting properly. You googled for a solution and here are some answeres. "Answeres I didn't have" when I had the problem.

These are keywords used to get you here when you googled your problem, Please Excuse them.

Some 4.3's have 2 Coolent temperature sensors, Some only have 1. On the engines that contain 2 sensers, One is a Temperature Senser and the other a Temperature Switch.

The Temperature switch Is an open circuit, It closes at a high degree.

The Temperature Senser, It can Advance Timing, De-advance timing, Control your Fuel to Air ratio and much more. 9 Times out of ten if your truck is stalling, its the temperature senser.

Which one is the Senser, which is the Switch? The temperature Switch, Which is the minor of the 2, It has one "Vertical Pin in the center of Plug Housing." It is used only for Plug guidence. The smaller *** close to the center *** is the connector ***. It is where the 1 wire makes contact.

The Temperature Senser, Rather than switch has 2 side by side Vertical Parallel Male Titts. It also has 2 wires.

Some engines Do not have a Temperature Switch, The switch on these are built into a temperature senser, and a switch is not needed.


These are the "Symptoms" of a faulty temperature Senser.
Surging
Loping
Sudden shut offs at stops
Transmissing jerking, Leight or violent.
Missing
Missfiring, Since the senser Does control Timing!
Fluiding, Wrong Fuel to air Ratio, The senser controls that to.

Rings for your Vortec. If you can't find the rings you're lookinf for, Chances are " PERFECT CIRCLE " is the only Brand ring you will be able to find without paying the dealer price. Which Perfect circuit runs around 60 to 70 bucks for the hard to find rings that you thought was impossible to find.

(PVC valve can cause Smoking." And rough idle as well. But loping is mostly due to temp senser.


Vortecs have very few sensors. If any of them go out the BRAIN is "PROGRAMED" to cause a ton of trouble. They are Designed to cause you to spend your money.

Temp Senser, Code 15, Not all BAD temp sensers Shoot a code, Sometimes these Bad sensers Do go under the radar and the error anylizing doesn't work, and give code.

You can not test a Temp senser with an ohm meter, Because at different temps you get a different reading. If you suspect this type of problem make the senser number 1 on your list to replace.

The part is 12 bucks at autozone. $12.00 and you should not pay no more than 35 dollars to have it put on are you are getting ripped off very very very badly, Since that is "More than what its worth" to have it installed.

The vortecs with No temp Switch will have the senser located in the driver or passenger Head. Engines with switch sensers will have the switch on the head, and the senser by the Thermostat duck goose neck, so a hose may have to be removed along with a throttle cable and top breather.

Spider leaks due to lines or regulator, where regulator is not part of the spider and can be removed, regulator can be purches on the internet threw search engines for 50 bucks. Right clean intake equals bad regulator left equals bad supplie lines.

Supplie lines and clamps can be purchease under 3 dollars, hoses made for gasoline. Ports leak into cylinders.

Some engines have abnormal cylinder locations such as 135 or 153 and 642 or 246. Accorrding to the book of the cylinder locations mines are different. This is abnormal but those engines are out there.

If you're having problems with firing, Cross 2 and 6, then 3 and 5. Doing this will reveal the right locations over time. This can leave you scratchign your head when all you're finding is 1 diagram thats not for your engine.

"The Poppet Valves DO NOT leak inside the intake." What Idiot ever started that. They leak inside the HEADS. The Regulator and Supplie lines leak inside the intake. Rarely do you need a entire "Spider."

Caution, Spider lines are Fragile and will break like glass. Do not bend them any.

How to install Supplie line hoses to the spider. Insert the washers First, Then insert the feed lines. DO NOT insert the supplie lines if they contain a washer already on them, They will not fit. You must first Push the washers Inside the spider, Then the feed lines will go into the spider, and as this happens the washers will slide up onto the lines, This is how it is done. User a lube, Gas or PB blaster Oil or whatever.


IF you run into the store, come back out and your engine fails to start, It's probably your Senser if you can't keep it running. If you manage but it stinks, its probably your spiter. You can also Hear gas leaks inside intake. Cap can be removed to see inside intake, Intake shouldn't be too clean which would indicate gas cleaning.

Confirm fuel pressure reading with a gauge. Post the psi readings. Confirm spark is reaching the plugs. Ignition coils and modules are a problem area in these cars.
