Fd afr problem
Hey guys I am having a slight problem with my AFR's when I am driving at a constant speed in any gear. It seems that it spikes lean and then back to normal constantly until I give it more gas. Afr at idle are good just seems to spike lean then back to normal and continues this way until I add more gas then it is good
I have checked and adjusted the tps and it's in spec but could it still be faulty?
I made the fpr vac line go to front of manifold
Appreciate any input. Im suspecting the fpr is bad

Sorry by adding more gas I mean pressing the pedal down more. AFR's are good at quicker acceleration but at a constant rpm it jumps from about 13.5-16 constantly back and forth, you can feel this surge within the car

Car was almost stock minus cat back when problem was occurring as well, any rpm at constant throttle is only time it happens. Will be getting it tuned hopefully by you Marco but was trying to fix this issue before

I've seen your exact problem more then once. Tuning fixes it every time. That is why I'm being so direct :P
Other then that, try a quality injector cleaner like Royal Purple? These injectors do clog up after all these years and I've seen 20% changes in fuel demands after cleaning stock injectors (actual cleaning, not injector cleaner).
