| Toyota Corolla 1999 or Y2K gas pedal issue? There are times when..
#1 The engine is running
#2 The car is in forward gear (not park, neutral, or reverse)
#3 I am not applying any brake (foot or ER!/Stat!)
#4 I am stepping on the gas
And yet the car does not move or it moves, it moves as if I only released the brake of the car.
*
Do you have any ideas of:
#1 What that might be?
#2 How much will that cost to fix?
#3 If it requires a car pro look at and fix it OR can a non car pro (such as my self OR my dad) fix it?
Thanks.

kudos:2 | When you're stepping on the gas, does the engine rev/ increase RPM? Do you use the Ebrake a lot, or just occasionally?

Yes but also no.
No when I am having this issue.
said by Juggernaut:Do you use the Brake a lot, or just occasionally?
I try to use it occasionally as I can. There are times when the brake is used more than occasionally.
said by Juggernaut:Do you use the EBrake a lot, or just occasionally?
If by EBrake you meant ER!/Stat! brake, occasionally to never.

kudos:2 | I ask those questions, as I was wondering if your parking brake may be dragging, perhaps.
As for the engine revving, I wonder if it may be the TPS (throttle position sensor). Does this happen when hot, or cold? Or, does it matter?
Although I'm not familiar with this vehicle, I'm just thinking out loud here. Some symptoms transcend makes, and models.

Please explain, more in detail what you mean by that.

Unknown at this time, but seems like when the engine is hot.
If talking about the weather, again same thing.
Why unknown at this time: It started recently in 2012. I can't say this will happen in the Winter time too..

kudos:2 | Well, if it didn't move forward by itself, it may mean the brake was dragging. But, that doesn't seem to be the case here.
Heat tends to take it's toll on electronics under the hood. That's why I asked.
• is the check engine light on?
• was the vehicle boosted, or gave another vehicle a boost?
Probably the best thing to do is take it in to a shop to have an OBDII scanner put on it. I think I remember a few folks here saying Pep Boys? does it for free.
PS-I was hoping a few other regulars like Mattmag would jump in by now. Sorry I couldn't be more help.

far as i can find real quickly, it's not electronic throttle(99 model), so it's a physical linkage between the pedal and the intake, might want to check the condition of the cable. |

Re: Toyota Corolla 1999 or Y2K gas pedal issue? I'd check the 8th gen Corolla forums at ToyotaNation: »www.toyotanation.com/forum/131-8···98-2002/
Bennie, LeakySeals, and a few others there really know their stuff. Watch out for KeMBro2012, tho, I heard that guy's a real jerk; you might see him on here, as well, he sometimes goes by BronsCon.  |

A physical linkage between the pedal and intake means it will work or not work at all, nothing in between.
So I'm thinking sticky valve in the throttle body or dirty injectors.
How's the idle? Is the RPM steady and stable?
If it's an automatic: Does releasing the brake let the car move forward even when not pressing the gas?
If it's a manual: Can you recreate the problem (RPM wise) while in neutral?
If you GET it fixed by a "normal" mechanic, he'll have you replace something instead of cleaning up/fixing what's sticking.
said by aefstoggaflm:#3 If it requires a car pro look at and fix it OR can a non car pro (such as my self OR my dad) fix it?
By non-pro, do you mean you and your dad are pretty handy with car repairs, BUT don't have all the equipment and knowledge of a professional mechanic? or you mean you guys have a hammer and screw driver and that's as far as it goes?
Bottom line: Something's dirty and sticky. Considering the age of your car, I recommend you give a try to using seafoam in your fuel tank and throttle body. Google guides for seafoam in fuel and seafoam in the throttle body.
Also I recommend finding a popular toyota corolla user forum and finding the subforum for technical support on your car's make and year. There might already be a lot of people who had this problem and found the solution. |

Worn throttle position sensor and/or dirty throttle body sounds likely. |

Nitpicking here, but not completely true. I had an E30 BMW the had two or three strands of throttle cable fray off and over time would make the throttle stick in various positions (which I ignored, being the stupid youngin I was), including WOT (which finally made me fix the problem...ever hear a BMW M20 engine redlining? it is both a beautiful and terrifying sound  ) |

That must have been dangerous though because you could get stuck in PEDAL TO THE METAL position  |

No it was not, but it turned on yesterday afternoon.

As far as I know, no.
That is unless my parents got one for my car / gave one from my car, but did not tell me.

For all we know, the ECU got a code from another part that reacted to the real problem. |
|
| It won't throw a code.
The intake bellows is cracked &/or split.
Common problem on this vehicle, in fact, most any japanese vehicle of the same era.
The throttle will work normally, but the air leak in the bellows will not allow the MAF to sense the engine is trying to pull air, so it adds no fuel.
Rubber intake bellows are not cheap, maybe 100$ for a 3" x 18" tube, so be sure. |
