Without a scan tool, the only way to find the problem is to check the basics and research common problems with your particular car make, year and model. I'm having the same problem with my 2000 corolla. So far it hasn't come back. My mechanic called and told me there was a service bulletin for this problem. My wife bought a new air filter because I thought it could have an air leak. Does anyone know how to repair this. I have also read on other forums that there was a recall for the fuel injectors in some of the 2000 Toyotas.
He said it was running lean at all times. Went for a 160 mile drive the next day and a several short drives over the next few days. We couldnot isolate between the sensors and I did not want him to guess. Really, you cannot expect to get any significant service from a new car dealer for less than a few hundred dollars. Test drive went well and it idles much smoother now. Disconnect this hose from the intake manifold also.
She only drives in the city too. Just those 4 hoses, and I also cleaned up the throttle valve and body. The first two miles of driving had very rough idling, but it seemed to ease up. I started Googling and came across this site. I buy some fuel injector cleaner and disconnect the to clear the light.
There is nothing more satisfying than seeing that check engine light go away with such an easy and cheap fix! At 180K miles, I'm certain I'll be turning them into powder. My question is, do I really need a special tool for the spring bolts? I live in Las Vegas so thats why it gets so hot. In fact I took my time and cleaned out the throttle body and the intake manifold while it was apart. Remove the battery negative cable. At first I thought it was the intake manifold gasket, swapped it, not the problem.
My question is, do I really need a special tool for the spring bolts? I got my entire set and the 12mm socket worked perfectly. Those gaskets fail all the time. A local garage will usually read the codes for no charge in the hope of getting the work. I plan on putting in new spring bolts and gasket between the manifold and the frontpipe as well as replacing the front o2 sensor. I get so sick of dealers and they would not let me talk to a mechanic.
Same problem with Corolla 2006. Took my 07 corolla to the dealer and the receptionist said it may be the intake gasket though Autozone clerk was very skeptical on that. I drove with it on for a few months and several thousand miles with pretty much no problems. I'm having the same problem with my 2000 corolla. We hope that will turn it off this time. I recommend changing the battery and you should see an improvement. Tried putting in fuel additive again but the light remains on.
Three months ago the light comes on, I bring it in and they find code P0171 lean Condition Freeze fame shows very high trim values. Much appreciated was that he got the parts to be covered by Toyota and I just had to pay for the labor only. In this instance p0171 code only happened after warm up, at idle. Still no fluid came out. Takes a little bit of working it to get it in and out.
Fuel pressure could be faulty to where on of your fuel injectors are bad, Air fuel ration sensor or 02 sensor, a leak coming from the exhaust system. The zirconia generates voltage from approximately 1V in richer conditions to 0V in leaner conditions. I got mine on and off--albeit with some difficulty and stripped threads--with just a regular socket+ratchet+extension. Before these repairs were made, the check engine light would only light occasionally and the symptoms would only appear intermittently. Also check the air filter for holes or debris, sometimes mice get in there. My question is, do I really need a special tool for the spring bolts? The only job the rear O2 sensor does is monitor how effectively the catalytic converter is doing its job.
