Low power and stalling
Hello
Everyday i use my svx at least twice.And the second time around, problems happen. WTF? So today, I drove it for about 30 minutes, no problems at all. Three hours later, gotta go get my girlfriend at work. The car starts stalling when coming to a stop. Starts and drives fine after that.But it keeps losing power (i.e: turns completely off) when driving at stable speeds, but catches up right away if i push the gaz pedal... I heard my belts squealing, so I tighened the tensionner. But it still stalls once in a while and keeps giving me less power than it should. I don't understand why the car would drive fine for a full 1 hour ride, and then start giving me troubles.I am sure it's electrical.I found out that the guy who fixed my rad fans connected a wire from the positive of the battery to the fusebox. Also, I've tightened the battery connections since they were a little loose. that gave me 2 days of tranquility.then my problems came back. I am getting tired of it. Please help, I love this car, but it is becoming erratic. |

MAF? (Mass Air Flow Sensor)

Re: Low power and stalling
MAF. Exactly what mine did when the MAF failed.

Re: Low power and stalling
I have changed the maf last month. The problem is the car runs like it misses fuel sometimes, or doesn't burn its fuel properly.I should change the fuel filter I guess, and check the fuel pump..

Re: Low power and stalling
Did you change it to one that is known as being good? Because what you're describing is exactly how misbehaving MAF's act.

Re: Low power and stalling
Is the Check Engine light on at any time or have you looked for history codes yet? I would start here

Re: Low power and stalling
Bad ground maybe?There are no lights on the dash, I tryed getting the codes yesterday, but I'm doing something wrong..Forget the maf, its good.Also, I hear some switch or relay flicking quickly for a few seconds at a time behind the dashboard.Seems to me like a bad connection somewhere..

Re: Low power and stalling
awesome, will do that tonight.Sounds like it could be the solution to a few problems.Like yesterday, it misfired on one cylinder for a few seconds, then it was ok again..

Re: Low power and stalling
what about the sensors under the intake manifold? my sisters svx is doing the same thing. when i took the manifold off i noticed one of the sensors broke then when i put it all back without the sensor, the car started to have the same symptoms. i still need to get them ordered...

I believe the more acceptable way to say this is "mentally disabled" the timing. Sheesh!

Re: Low power and stalling
Yes and no. It is possible for the sensor to be cracked (plastic case) and it won't throw a code but it will cause the sensor to read wrong or different than what it should.
