Engine corolla 2000 ce starting problems

corolla 2000 ce starting problems

hi i have a corolla 2000 ce and when the car is cold it starts and drives great,but when the car gets warm or driving for a while and i hit the gas a little more than normal it bogs chokes? and if i shut it off and try to restart it it wont start until it cools down.the check engine light is off i did have the computer checked for error codes and everything is ok the guy told me.the car has 47k miles. any ideas would be a big help thanks so much.p.s. the engine turns and the battery is good when trying to start warm.

Umm, how bad is the bog? Is it only from a dead stop, or does it last through the entire RPM band?

How hot has it been lately in your area? My guess would just be heatsoak of your intake. It happens to my car too and will sometimes bog a bit from a dead stop.

hi renfield its a bad bog almost cuts off the car ,the weather is was cold 20-30 degress and now its getting warmer 45-almost 60 degress outside it does it all the time its getting worse becuase the weather is now getting warmer its taking longer to start becuase the weather is getting warmer now it just started happening about a little over 2 weeks now all the time.p.s. i bought the car in 2000 and no problems summer or winter just now

Check your air filter...could be clogged.

Clean the MAF sensor...it can cause your car to run lean.I can give you directions to the MAFS and how to clean it if you need it.

When was the last time you ran fuel injector cleaner? Some of that might help. Also there's a thread in this forum about cleaning the PCV valve and hose, that could help you a little as well.

Clean the throttle body if your problem hasn't improved...and do it properly by disassembling the throttle body, the stick-and-spray method doesn't work too well.

Anyone else have any other ideas? If all else fails, talk to a good mechanic about this.

I dk man to me it seems maybe a problem with a temperature sensor or maybe the thermostat or somethin....

hi again reinfeild90 i did check the air filter it looked clean i even took the air filter out and put the cover without the air filter just to try it it does the same thing i have to try the fuel injector cleaner and pcv valve i dont know where the mafs sensor is ill try and see what happens thanks again for your help.

hi Cuztomrollaz98 i downloaded a program called auto tap and obd11
i have a laptop all i need is a serial cable i did some research i think my car is a iso type ISO9141 if all fails ill take it to another auto repair shop when i could get some money together.thanks for the help can the temp sensor be tested?thanks again

hi corollasbest thanks a lot cool site thanks.

all

hello i bought the car to another mech he scanned the computer and everything
was good well he found the problem it was the air flow sensor.thanks for all the help.

run seafoam through the intake, theres a thread on here about it. you'll notice a difference

The MAF is right on top the air box, quick replacement. When my MAF was bad I had a CE light after accelerating intermittently, no change in performance, light would return after reset with battery disconnect. New MAF and no more CE.

^^ That's right, you'll see somewhere in the airbox or intake tube a little something that plugs in, with wires coming from it. Sorry I didn't respond sooner, I got caught up at school a bit. To clean it, you remove it carefully (they are expensive, and break easily) and spray a lot of throttle body or carb cleaner over it, and let it dry.

If you haven't replaced it yet try cleaning it first. I think they're around 300 bucks for a replacement, and a bottle of TB cleaner is about 3 bucks. Be sure to reset the ECU by unplugging your battery for 20 minutes, so the ECU can start mapping the correct readings from the MAFS from scratch.

my car actually did do that too.. but I didn't change the maf.. I just cleaned it
