91 camaro dies

my friends got a 91 camaro,it starts up fine,drives fine,but when hes at a red light it seems to stall down & die,when the engine is cold it wont die,but when its warm it will,I've replaced the fuel filter,ive had the fuel pump checked out & its working fine,ive had the coil checked out its fine,we did put on an aftermarket air intake & the factory intake had a iat sensor & its not connected to the air intake,so that may be the problem,but if you have any information on what it could be,it would be helpful

we did put on an aftermarket air intake & the factory intake had a iat sensor & its not connected to the air intake,so that may be the problem,but if you have any information on what it could be,it would be helpful

there is the problem, need to get the iat sensor reconnected.

WHERE THE HELL DID YOU GET THE AFTERMARKET INTAKE...lol i have looked everywhere :P i have a 91 camaro as well and i have the same opinion get the sensor reconnected

plug that IAT in and you'll be golden...

if not the that sensor, try the oxygen sensor. it might be bad, it does not affect engine operation until the engine is warm (in closed-loop). Someimtes the check engine light will not turn on even if it is bad.

check engine won't come on if the injectors are bad either.

check the o2 sensor

if it ran ok before you put the new intake on then theres your problem. plug in that IAT.
