Engine will not Idle?

My problem is this:
My car seemed to be running and driving fine when I left work yesterday, got it on the highway home and still all was good. As I took the exit off the hwy and came to a red light, I put the brakes on and the car shook and died. I put it in park, started it but as soon as I put it in drive it stalled again. It runs fine in park, reverse and neutral but stalls immediately when engaged in drive, first or second. I even tried having one foot on the brake, revving the engine with the other foot and throwing it in gear. That didn't work.
Can you give me some ideas as to what the problem may be and an approximation of how expensive it will be to fix.
Thanks in advance :)

It sounds like it might be the tcc solinoid. You could try unplugging it. I think it is located on the driver side of the transmission toward the front. Had same trouble with a Berreta. That fixed it.

When we put engine in gear it stalls and shuts down

I have a '95 Chevy Z-71, 5.7 v-8, with approx. 187,000 miles on it. My problem is that it keeps wanting to die when idling and when I come to a stop. It won't do it all the time and it doesn't matter if it is hot or cold. Always starts back up then dies again when I come to another stop or when idling. Already replaced: TPS, IAC valve, distibutor, distributor cap and rotor, plugs, fuel pump, fuel filter, cleaned throttle body, reset timing, new computer. I think that's all. I've done alot to it, and it's still acting up. I've had 8 mechanics look at it, and they can't figure it out either. All ground wires are good as are the wires in the ignition. At wits end! Help!

We have done all those things. No leaks. Still acting up!

Engine won't idle. OBD1 codes 43 and 71.

My chevy pickup starts then stalls ---runs very rough and stalls----i cant even put it in gear (automatic transmission) it stalls---i have to pump the gas to keep it running at all and it is extremly rough and still stalls ---when it stalls it appears to make a hard air sucking noise----i have checked the codes and have replaced the map, oxygen sensor, tps, iac sensorsi cleared the codes and retested and it only shows the code 12 nowi checked for bad or contamination in the gas --appears ok---i replaced the plugs wires cap and rotor less than a year ago----what could the problem be help please before this thing breaks the bank :oops:

It sounds like you have a clogged fuel filter [most likely] or you may have a vacuum leak around the throttle body or intake manifold. The fuel filter is under the box on the left side frame rail. Make sure you remove your filler cap and disconnect your battery before you start. This relieves the pressure in the fuel line. You could also check the torque on the throttle body mounting bolts. Should be 12 ft. Lbs. Hope this helps.

I checked and could not find a vaccum leak---and the fuel filter I had already replacedthe hard vaccum sound only happens when it stalls out.

It really sounds like a fuel supply problem. Maybe a bad filler cap[too much vacuum in tank], pinched fuel line, or weak fuel pump? Do you have any way to check the fuel pressure? Should be 9-13 psi. Also there is a whole slew of other sensors. If all else fails, get it plugged into a diagnostic computer to be sure.

After replacing the iac sensor. Map sensor. Oxygen sensor, fuel regulator and injectors on the tbi, fuel filterit still did the same thing---the sensors where replaced by testing and retrieving the codes----codes 12, 22, 32, 33, 44---which lead me to replace those sensors. And still not getting any results except that the codes nolonger came up with the replaced sensors ----then I did another code test and a new code came up code 54----didnt show up on any previous tests, FUEL PUMP :o --i replaced the fuel pump in the gas tank and then it wouldnt start at all---so apart it came again to recheck the instalationneither old or new pump would run when I tried to bench test it ----so I got discouraged and just left the new pump in and put it all together again---ouch bleeding profusley from my knucle busted hands ----all connections wwere properly connected the first time and the second time---to my suprise it started after reinstalled and runs greatmust be the truck gods dont like me :twisted: ----well at least im up and running again ---thanks for the help :D

Good to hear you got it sorted out. I'll keep my fingers crossed for ya. Hopefully it's all smooth sailing from here. :D

I have a 1995 Chevy s-10 (170,000 miles) that won't idle when cold and runs rich.

Here's what I have done so far:

Changed the distributer, wires, plugs, rotor, cap, cooling temp. Sensor, idle air control, computer (but not the PROM chip), and coil. The fuel filter has been changed, there is no water in the gas and I have checked the ignition timing.

The spark coming from the coil to the cap is blue, but the spark coming from the end of the wire to the plug is orange. Also, I cannot pull an error code from the computer, I am getting a link read error instead.

When it does run, if it ever backfires when shutting off, it won't idle when started again. If it does start, I can bring the RPMs up, make it backfire, and it runs fine.

Any suggestions?

Have you changed the fuel filter lately? Is there water in the gas? Have you checked ignition timing?

What engine is this?
