HI I new to the board and this is my first camaro I have a 92 camaro rs 305 tbi idles ruff and dies at a stop acts like flooding boggs down when give it gas
i have replaced the air filter fuel filter and pcv valve ant the coolant temp sensor same prob
i can unplug the tps the map and the coolant temp sensor and it runs fine
i can plug up the coolant sensor and the tps and and the idol is fine when i plug up the map it starts surging and dies after it runs for about 10 to 15 min i can drive it but if i have to come to a complete stop it stalls after i drive it a few miles sometimes it will run ok others it keeps stalling

 

sounds like its a bad MAP sensor, i mean if its unpluged and runs fine then you plug it in and it dies it would tell me that its the MAP

 

ok thanks i have a new one on the way
ill keep posted

 

OK replaced the map still same prob except wont run with the tps plugged in plug it up and stalls and as long as i have the vac line to the map and the tps unplugged run good can drive it some cant give a lot of gas at a time do to it starts backfiring

 

We replaced the IAC on my sons 92 TBI 305.

Now his coolant fan and the blower for inside the car doesn't work. Taking car to the dealer tomorrow to figure this one out.

 

I am having the exact same problem and suspect the throttle position sensor. I only have problems on warm afternoons, however. My local mechanic wasn't able to diagnose the problem. Please let me know what you find!

 

Well i had the same problem and i swear it was like a phantom problem. The car would run fine for a while then die when i hit the gas. I replaced every sensor in the car, the prom chip, the computer itself, i mean everything. finally i sent the car to a mechanic and it was the wires that connect to the coolant tempature sensor. If they are bad or are shorting out they cause the injectors of the car to go pig rich.
If the sensor was totally shorted or disconnected it would show up on the check engine light. But in my situation the sensor was working but was telling the computer that my car was in negative 33 degree weather causing the car to go super rich.
All the super camaro freaks out there say that can't be causing the injectors to do that but after the wires were fixed my car was purring nice.
Oh i forgot to mention, my car would only do it on hot days at first also. it got worse over a week or two time frame

 

thanks ill ck the wires I did not think of that

now it don't want to stay running at all but it is getting low on gas
but ill go ck wires tonight when it cools down its above 100 here to hot with no shade

 

ok i have found a wire that has pulled out of the connector on the passenger side below exhaust manifold any ideas what could be to

 

Well i have a 91 Z28 and the O2 sensor is on the driver side so i have no idea

 

That could be the cooling fan switch. I had some problems with that one.

 

i am about ready to swap to carb and do away with the electronics
i have had this car for 5 months now and have drove it less than 200 miles
it ran great for the first 2 weeks then went to having a small prob but could drive it now wont stay running

 

As far as I can see in this forum this is VERY common problem for v6 and other engines when you ride at 20-40 km/h and engine dies despite of smooth idle at park. With my car I had the same for a pretty long time. Now the problem is resolved.

Here is the procedure.

Conditions:
1) correct spark advance
2) no ignition problems (good plugs, wires and distributor)
3) no big vacuum leaks
4) good IAC
Now to do:
1) screw out throttle adjustment bolt untill throttle is completely closed
2) turn on ignition and wait 5 sec.
3) disconnect IAC plug
4) run the engine
5) turn throttle adjustment bolt untill engine revvs up suddenly (you need to find this threshold) and add 1/2 turns more
6) shut off engine
7) connect IAC
8) disconnect negative battery cable to reset ECM
9) connect battery
10) run engine

That's all.

p.s. the problem was in incorrect throttle adjustment.

 

i got to cking vac lines and had 2 disentagrate in my hand so gotta replace them before ant more trouble shooting can be dune

 

90-92 v6 camaros hate vacuum leaks..check the brake booster,the fuel pressure regulator,and the divertor valve.My car died at every light and my booster was junk..I played/replaced with every sensor with no change.The fuel regulator and divertor valve are tied together by those cheap plastic lines that everybody touches and it breaks.If you have no check engine light I would say you have a vacuum leak.

 

the car will now idle OK with the vac line to the map sensor and the tps unplugged if you plug up the vac line the rpm will go up and down till it dies if you plug up the tps it will rev up and die and you will see gas spit out of the throttle body
gona look for a intake and carb at a wrecking yard
