blackes2000 Posted May 16, 2005 Share Posted May 16, 2005 Hey all, I have a 2000 ES w/ almost 90'000 on it. Lately when I start it , it will turnover, RPM's hit 500 for a second and then it stalls. It is cured by stepping on the accelerator to get the RPM's up to idle, then it's fine for the rest of the ride and there is no stalling at all. This just started happening and it's erratic, it does not happen most of the time. Any idea what this could be? Quote Link to comment Share on other sites More sharing options...

blackes2000 Posted May 16, 2005 Author Share Posted May 16, 2005 No, I was surprised about this. I don't think it could be a major problem but I just can't figure what it is. I haven't done much work on this car. I used to do all my own work but now I live in the city and don't have a driveway. Quote Link to comment Share on other sites More sharing options...

mehullica Posted May 16, 2005 Share Posted May 16, 2005 Sounds like a bad idle speed control motor. Quote Link to comment Share on other sites More sharing options...
exdotcomer Posted May 16, 2005 Share Posted May 16, 2005 Sounds like a bad idle speed control motor. ← what kind of gasoline do you use? Have you used injector cleaner?how are the plugs? Quote Link to comment Share on other sites More sharing options...
blackes2000 Posted May 16, 2005 Author Share Posted May 16, 2005 I always use premium gasoline. Plugs and wires definitely need to be changed out. I picked up some iridium plugs but just haven't done it yet. I have not put any injector cleaner in it. Can you recommend an injector cleaner?

steviej Posted May 16, 2005 Share Posted May 16, 2005 sounds like a combination of dirty IACV (idle air control valve) and throttle body. Common problem, as the miles go up, carbon builds up on those items. Rough idle and no start conditions are usually the symptoms. The stomping the gas pedal points me to the IACV. Do a SEARCH on "control valve" over the past year just in the ES thread and you will see what I am talking about. both can be cleaned manually or professionally. You may also want to consider having a motorvac done (speciallized service that cleans the entire top end of the motor). You have to hunt around for a shop offering this service in your area. steviej Quote Link to comment Share on other sites More sharing options...
blackes2000 Posted May 16, 2005 Author Share Posted May 16, 2005 Thanks steviej. I'll try that out. blackes2000 Quote Link to comment Share on other sites More sharing options...
blackes2000 Posted May 24, 2005 Author Share Posted May 24, 2005 Well, I just got the motorvac service. $85 to plug this tank into one of my intake hoses and run the car for 30 minutes. The problem ceased for a week then I had an incident yesterday but the car never stalled. the idle just crept along at 350 then I gave it the gas. So basically it has made the problem occur less. I am now going to put in iridium plugs and new wires and see where that gets me. I have to change the timing belt in two weeks so I'm trying to not replace the IACV if I don't have to. Of course, the mechanics want at least $500 to replace it. May have to do it myself. Quote Link to comment Share on other sites More sharing options...
SKperformance Posted May 25, 2005 Share Posted May 25, 2005 The throttle body may need some more cleaning. As a motorvac cleans everything that comes into contact with gas not air. So the throttle body is before them and is cleaned by a can sprayed by the tech. It probably needs to thave the secondary bypass recleaned. Take it back and mention it to them, they might redo the throttle body for free. Quote Link to comment Share on other sites More sharing options...

Speakign of which, do I need to take off that plenum to get to the rear plugs? Quote Link to comment Share on other sites More sharing options...

Has your problem been solved by changing the plugs or otherwise? Quote Link to comment Share on other sites More sharing options...
blackes2000 Posted July 18, 2005 Author Share Posted July 18, 2005 Hmac, My problem occurs much less now. Probably once every 3 weeks. I was changing the plugs last night when I went to pull the coil off and the clip broke off. I'm hoping that the new plugs add to the problem occurring less. I would start with a motorvac service, it cleans your whole upper throttle body. That's what helped me a lot. Quote Link to comment Share on other sites More sharing options...

I'm going to have to bring it in and I'll talk to my guy about that (unfortunately I don't have the skill to get under the hood like you do). And I'll keep you posted as to how things turn out.
