Sounds weird, but if the check enging light is coming on that means the system has CEL codes stored which could point you in the right direction. Pull the CEL codes and see if that helps. There's a list of CEL codes for S5's in the Factory Service Manual.

Oh yeah. The next question is "How do I pull the CEL codes on my S5?" Go to www.banzai-racing.com and click the link to Tech Support in the left hand column list. This is probably the best step-by-step that I've come across.

Ah, yes! The TPS. Most RX7 oweners don't realize the number of problems with idle and acceleration an out of adjustment TPS can cause. At least at every oil change a TPS check should be done. Then, when something wierd pops up with engine performance or idle, the first place to look should be TPS setting.
