-- Posted by JulieisWHOA at 2:20 pm on July 6, 2008 I have a '95 Chevy Cavalier, and sometimes when I stop at a light or a stop sign, it will kind of shudder and then turn off. I will have to put it in park and crank it back up. Usually it cranks right back up, like it did today at a light, but then I had to stop at a stop sign and it took me three or four tries to crank it back up. I was wondering if anyone would know what was wrong with it...My grandparents are saying maybe the fuel injector, but I have no clue. It just sucks having a car I'm scared to drive. And it doesn't do it all the time, just sometimes. It can go for weeks without doing it at all, and then it can do it several times in a row. -- Posted by ManicD at 2:22 pm on July 6, 2008 its proberly "idling" too low, you'll need to adjust teh idle speed, in an old car like that it should just be a basic bolt and retaining nut -- Posted by JulieisWHOA at 2:36 pm on July 6, 2008 My boyfriend is saying that "idling" too low could be a problem if it was a carburated engine, but since it is fuel-injected, he doesn't think that could be the problem. -- Posted by ScoobyDoo82 at 2:37 pm on July 6, 2008 My sisters 98 Cavalier has the same problem, try putting premium gas in it, its more expensive but it helped my sisters car, it doesnt stall anymore. -- Posted by JulieisWHOA at 2:42 pm on July 6, 2008 That's what my grandpa was saying...He was telling me to put the fuel injector stuff in it and maybe that would help. I'm just so broke. lol. I can't afford premium gas...but I may try that. -- Posted by tempoluvver69 at 2:47 pm on July 6, 2008 for a start clean the mass airflow sensor if it has one. If its really dirty it can cause idling problems. Is the check engine light on? If so take it to a auto parts store and get them to run the code. Oxygen sensor is also a possibility -- Posted by JulieisWHOA at 3:07 pm on July 6, 2008 My boyfriend said no to those two, and the check engine light isn't on. -- Posted by tempoluvver69 at 3:38 pm on July 6, 2008 Quote: from JulieisWHOA at 3:07 pm on July 6, 2008 My boyfriend said no to those two, and the check engine light isn't on. well then get your boyfriend to start throwing parts at it before trying to clean the maf which costs about 5 dollars for a can of cleaner. -- Posted by Holden Commodore at 5:47 pm on July 6, 2008 Quote: from JulieisWHOA at 3:07 pm on July 6, 2008 My boyfriend said no to those two, and the check engine light isn't on. Your boyfriend apparently doesn't know jack fucking shit about cars then. What you start with, is the mass airflow. If it's stalling, you COULD be having a bad reading from that sensor. That is why you have it cleaned. If that doesn't do anything, the next thing is checking idle speed. Does it stop running in park, or only while in D, 3, 2, or 1? (You could maybe not have a 3, but only D, 2, 1 depending on the cavalier's transmission. The next step would be checking your fuel filter which is under the car. Bad fuel flow at low rpm's could starve the engine of fuel, and it would just shut off. Don't ask questions and then say it's not it, when you haven't even checked the car :/ -- Posted by Holden Commodore at 5:47 pm on July 6, 2008 Quote: from ScoobyDoo82 at 2:37 pm on July 6, 2008 My sisters 98 Cavalier has the same problem, try putting premium gas in it, its more expensive but it helped my sisters car, it doesnt stall anymore. premium fuel does nothing except prevent knock due to higher octane rating. -- Posted by hinshawwrx at 5:52 pm on July 6, 2008 Seafoam it and clean your sensors -- Posted by ScoobyDoo82 at 6:51 pm on July 6, 2008 Quote: from Holden Commodore at 8:47 pm on July 6, 2008 Quote: from ScoobyDoo82 at 2:37 pm on July 6, 2008 My sisters 98 Cavalier has the same problem, try putting premium gas in it, its more expensive but it helped my sisters car, it doesnt stall anymore. premium fuel does nothing except prevent knock due to higher octane rating.   Okay well all Im saying is, my sisters Cavalier had a stalling problem, she uses premium gas, now presto, it doesn't stall anymore. -- Posted by Holden Commodore at 7:19 pm on July 6, 2008 I know. I'm just saying, that.. that won't always work. -- Posted by coloring the void at 7:25 pm on July 6, 2008 Quote: from hinshawwrx at 5:52 pm on July 6, 2008 Seafoam it and clean your sensors I've heard good things about seafoam. Really does the trick in cleaning. -- Posted by Holden Commodore at 7:58 pm on July 6, 2008 i've personalyl never used it, i've heard good and bad both. -- Posted by hinshawwrx at 9:44 pm on July 6, 2008 I seafoamed the wifes Equinox, and it runs a bit better. It was fun blowing smoke everywhere for a couple miles. -- Posted by JulieisWHOA at 5:25 pm on July 7, 2008 I'm gonna check to make sure everything is cleaned and not clogged, get a new fuel filter, and research the sea foam. lol After the boyfriend said that wasn't it, he changed his mind the second I posted that. lol But yeah. I put in premium gas today. It was fine driving home, but I don't know. We'll see and I'll keep updates.
