I would have to agree on both counts. CEL should have been checked for codes and at least given credibility towards the symptoms. If the TPS is defective and the pcm believes the throttle isn't open all the way, it won't make a/f ratio adjustments.
IT thinks the the throttle is just cracked open a little it is reasonable to expect the engine will not increase rpms.
