Iam in need of some serious help. I just bought my Nissan 240SX and i have only had it for a week. I have just recently had trouble with it starting. It will start and then immediatly drop back down to zero and shut off. Also sometimes whenim driving the RPM's wont go they just stick at two and stop. The problem is on and off some times it starts perfect other i have to give it gas and other it wont start at all. I changed the spark plugs and took out some of the oil becasue thier was a little to much. I also added valve cleaner. Does anyone think it could be the regulator that gives the extra gas to start the car but it is just giving to mich or to little. Im in serious need of help and am looking for a solution.

 

its your mafs. make sure its pluged in all the way and its clean. im about 99% sure this is your problem. try it out and tell me how it works for you.

Its def your maf
My unle had that prob like last month and we unplug the maf then plugged it back in and started it

 

thats kind of a sad thing right there. i wish all problems were as simple as unplug-replug. ive never messed with my MAFs before (or any for that matter). anything special i should know as far as cleaning it?

 

Q-Tip clean it? Maybe you dont even need to clean it

 

k, just curious if it was sensitive to alcohol or anything like that. i dont want to try and be good with the cleaning and end up damaging the lil *****. thnx

 

well i took her to the shop and they told me that it was the temperature sensor so hopefully ill br driving again soon wooohooo
