Default PLEASE HELP!! LOOK HERE!!

Ok, I have a 90 Bonneville. My problem is my car stalls after about 2-5 minutes upon starting. I have replaced the throttle position sensor and the camshaft sensor. When I scan it for codes i get a code 22-Throttle position sensor low voltage or fuel cutoff relay. If it is the relay where is it? If it is not the relay what can I do to narrow down the prob. I have had the ignition module and the coil pack tested and they test fine. Any help would be much appreciated because this is driving me nuts. Please help me if you can. Thanks in advance.

Hey cronic_bob, welcome to the forum. There are people here who can answer almost any question you might have.

With that said... I have no idea about yours... Sorry.

you'll get help faster if this was in the 87-91 section, usually all the techs stay in those spots.....

Test the TPS by checking the DC voltage on the center pin - about .4 v at idle and over 4.0v at full throttle.

Stalling after 100ish seconds or coming to a stop signis usually a dirty Idle Air Control (IAC) .

If fuel pump relay(AFAIR is on the firewall above the HVAC blower motor), the rail pressure will be dropping.
