will it be ok to drive my car without the sensor in the downpipe? and that sensor that goes in the intake ?and the oil pressure sensor. will it drive any differnt except throwing a cel

 

yes it will trigger CEL

 

it will trigger a cel, and not having the 02 sensor in ( in the exhaust) could cause slight rich and/or lean conditions not a good idea to be driving it around like that, if you just need to get the car somewhere one drive will be ok as long as you take it easy, but if you want to keep driving it like this i would advise against it....
