so i take my car to the usual spot where i've always taken my cars...but yesterday they changed my oil and air filter..and the "service engine soon" pops out im due for my 30k maintenance next wknd..but should i wait? or take it immediately to the dealer? let me know guys its kinda freaking me out..its probably a sensor thing but i dunno..

the service engine soon light is the same as a check engine light bring it to auto zone and have them run the codes they will do it for free

^^thank you so much..will do that today

what does the 30k mile maintencne consist of?

also when changing oil how many quarts does it need, my mr2 used four, im not sure about the G.

Thanks
