[spyder2120]

hello everyone. im new here and i found this thread. ive been trying to soak it in but im no electrition. i have a 1991 metro with a pcv instead of an egr valve (if that makes a difference), and i want to install a kill switch. my question is; would the cam pos sensor be the way to go for me? in dont want any ecm issues or anything. also if anyone knows how to do the timing for this model please email me (spyder2120@yahoo.com). i have a manuel but it says to refer to the data under the hood. my sticker is mia. im not sure what tubes to block, unhook or anything else. the manual i have seems to indicate its different with every model. thank you.
