Question about 1994 Chevrolet Astro

1 Answer

Throwing too much gas - stalls.

Looking for any other checks I can do before assuming the ECM is bad.

Too much gas flowing to the throttle body from the fuel injectors. With both injectors in place, van stalls. If I remove either injector, van runs smoother, but not as it should.

Van has a TBI fuel injector. I have changed fuel pump relay. Good spark in the plugs. Catalytic converter checked - not clogged. The Check Engine Light is not displaying on the dash. I have not been able to get an error code to display when checking the assembly line data link.

Stalls out when the gas pedal is hit

Pull a spark plug. Is it black? Stalling on acceleration. Possible cause: vacuum leak; can be detected by spraying water on suspected area. Will produce sound as if drinking from a near empty cup with a straw.
Possibly throttle position sensor. When they go bad, they have a tendency to tell the ecm to release more fuel than needed, flooding the engine, and killing your gas mileage.

the iac code has nothing to do with the maf . the maf is your mass air flow sensor and it is in the air tube going to the throttle body. the iac is your idle air control valve that is in the throttle body next to the throttle position sensor

Replaced the battery in my 05 hayabusa now im not getting any power it won't start

Try to clean the throttle body air intake and rev it up a little there may be a blockage that the ECM may have been compensating for when you disconnected the battery the ECM will assume the throttle body is clean and closing fully but dirty carbon may keep throttle open slightly saucing rough running or stalling. Hope this helps

My 1991 dodge caravan is having issues. I thought it was in the fuel system so i changed my fuel filter,fuel pump relay and fuel pump. my van starts and runs but seems to stall out in 5 to 10 min. like its...

theres a few things to check for this problem. the throttle body needs a good cleaning, especially around throttle plate. I fixed a 95 caravan a while ago, and it would stall for no reason, cleaned out throttle body and now its fine. also a bad cam sensor will cause this as well as a bad idle air tcontrol sensor ( IAC ) try cleaning throttle body good. do this first ok ! do you have a check engine light on, if so have it scanned to find problem code. its very hard to tell by not being there but try above.

97 Ford Contour GL 2.5 L V6. Stalling out. Auto

They are not only for improving milleage, but play a crusual key for ECM to give out how much fuel to mix with air to have proper combustion hence not stalling when accelerated. But Oxygen sensors are expensive and even you have them replaced , this is not going to solve your problem since gum has built up at your throttle valve over the years. Have another shop to clean your throttle body first. Make an appointment so you can be there to see how dirty the throttle body is and also to make sure they actually take out the part to clean, not just spraying cleaner to the Air mass flow flap valve. After the throttle body cleaned, take off the battery cables for 30 minutes to reset the ECM to its default state so it doesn't use data from your current state. You will see an improvement. Afterward, the problem is still existing then Have Auto Zone store diagnose free for O2 problem before replacing them. Cheers.

2000 toyota corolla ve engine will run at idle but when you step on gas engine dies if you let off gas it stay running at idle got good fuel pressure good spark.i changed ecm changed fuel pump spark plugs...

Check the throttle cable to see if it's binding or catching on anything. If not, check the throttle body. If it's gummed up with carbon and not moving freely, you could be trying to add air that's simply not getting into the engine, while the computer throws a bunch of fuel in to match what it thinks it a ton of air.

Hope this helps.

Hi, Irratic revs when idle

You need to reset the throttle body. Sometimes you can do this by going out to your car and turning the key to the "on" position. Don't crank the engine - just turn it to on. Let it sit like this for 15 min. Your throttle body shoulld reset. Good luck. Check out audiforums. c o m or audiworld for audi spec issues. Good luck!

I just bought a used Ram about a month ago and we had to drop a new engine in it because it stalled everytime i hit the gas and then let off and two cylinders werent hitting. It has the 5.9L V8. However,...

I would look at the crank sensor or cam sensor,when the crank sensor in my ram went bad it would run when cold and then stall as soon as I put it into reverse,or when the engine warms up,check the ecm for codes,
