Recently read a post on another website about an oft overlooked MAF sensor and CRC coming out with a spray to clean it. If dirty, its supposed to give slightly better gas mileage which I for one, can certainly use. What and where is it ? Is it fairly easy to get at on an 89 2.9 engine ? How long would this take ? I normally use brake parts cleaner for almost everything. Would this work instead of the CRC ?
