Have Toyota Questions? Ask a Mechanic for Answers ASAP
THank you for using just answer.
A couple questions here:
-Which engine is in your Celica?
-Any check engine lights on?
-To clarify here- the car WILL stay running if you use the accelerator correct?
Peter, I replied to your follow-up questions almost an hour ago. If you don't know what the problem with my car is, please just say so.
You posted your question at the bare minimum $9 rate, you cannot expect a immediate reply unless you post at a $30 level, we have to help a lot of customers here.
There were 2 differetn 4 cylinders used in these cars, that's why I asked which engine you have, take a look under the hood at the emission label, you either have a 7A-FE 1.8L engine or a 5S-FE 2.2L engine.
THe questions time out after 24 hours but you as the customer have the ability to reopen them, you just did that by posting to me again.
I'm not asking you for a $21 bonus, I am just asking for some understanding if you did not recieve a reply in a matter of minutes.
I do have one last question for you on the car, does the idle speed seem to be very low when the car is running without applying the gas pedal?
ok, based on our conversation I feel that this is directly related to your IAC valve. This is an electronic control motor on the bottom of the throttle body that the computer uses to set the engine idle speed.
Once the car is warmed up and the a/c is not on your engine should idle at 750 rpm's when in park or neutral. A/c will usually raise the speed by about 200 rpm's.
What happens is over time the valve gathers carbon inside it and it fails to move when commanded. Sometimes you get lucky and you can have this valve removed and cleaned out, it has been my finding over the years that if you clean this valve out immediately once a symptom starts then usually you can save it. In your case I recommend that this valve be replaced. At the same time the throttle body and intake manifold needs to be cleaned out to remove all forms of carbon buildup.
Thank you for such a thorough answer. I just wish I understood the mechanics of it better. Is this a very expensive repair to make? And how much time do I have to get it done before the car conks out altogether?
This is more of an annoying issue then anything, if you stalled out in an intesection I guess ti could be a safety issue.
My recommendation is to print out this page with out conversation and that diagram above and bring it to your mechanic. Then get a quote from him. The valve is a couple hundred dollars, be sure that he also replaces the gasket that goes between the valve and the throttle. As far as labor, do not let him charge you any more then 1.5 labor hours to do this.
