please help!!!!!!!!!!

i have a 91 Camaro TBI 305 when you start it up to warm up it runs EXTREMLY RICH and eventually floods out

then if you hammer it after driving the service engine light comes on and it floods out

when it does this the throttle body whistles EXTREMLY loud

so far i have replaced the fuel pressure regulator
map sensor
coolant temp sensor (INTAKE)
fuel filter



could it be the injectors going bad?

 

what codes does it throw? What is your fuel pressure? Theres always the possibility that the one you where sold is set for an incorrect pressure. All that noise is probably all teh extra fuel squeezing throught he passages near the throttle blades.

 

It is VERY unlikely that the injectors are going THAT bad to cause such a rich condition that the car sets off an SES light and floods. I would do the basic stuff like checking fuel pressure and pulling the error code(s) from the ecm. I doubt it's the o2 sensor and that whisling is usually the IAC motor going crazy because some sensor is fubar.
Reply to this when you've got an error code then we can help.

 

ok guys thnx i will hook a scanner to it tomorrow

 

ok a friend of mine did the wire thing with the diagnostics connector


code 23
code 15

 

Check out the FAQ here, and look at towards the bottom:

https://www.thirdgen.org/newdesign/faq/thirdgen.shtml

Code 15- Low temperature indicated at engine coolant temp. sensor

Code 23- Low temperature at manifold air temperature sensor OR
Throttle position sensor error

Sounds like you may need a bew TPS since you already replaced the CTS. However, dont rule out that the CTS is okay.. could still be bad.

 

the coolant temp sensor is in the intake manifold and there is one in the right head right?

 

Here ya go, check this thread out.. theres a post about where the three sensors are. Also do a search in this forum for code 15.

looks like im gonna be replacing the one next to the thermostat

 

intank=comp
head=gauge

 

thanks a lot guys it was the coolant temp sensor in the intake manifold i can't beleive that tiny part did all that to that car well now i gonna replace all 8 plugs they are pich black


but at least the car is back to destroying Hondas
