definitely go to the auto parts store and get the code readings. being too lazy to research, what is the year make and model of the cellar car? a good friend, the same one that helped me swap transmissions, is very good at diagnosis and advice. when i get the Y/M&M i will consult him as well. if it is the injectors i recommend changing them all with new ones. another thing it may be is a bad cam position sensor if you have one on there. the Fixed Or Repaired Daily had that problem and would miss going down the freeway under stress (ie going uphill) but always cranked right up so maybe it'snot that. but worth a look see.
