Hello, just bought a 2006 toyota corolla with about 89,000 miles on it, 5 speed manuel transmission. Ive noticed that in lower gears, like 1st, 2nd, and 3rd, it kinda of jolts and lurches forward a bit when I left off the gas, and can really feel this in 1st gear, when I'm not even going 10 mph. This completely goes away when I'm out of gear, coasting in neutral. I should also say there is quite a bit of engine hesitation ( I press accelerator, RPM goes up about 1 sec later)...
I've cleaned the MAF sensor, and the throttle bottle and am about to try some royal purple fuel additive for my fuel injectors, but considering it goes away when I'm out of gear, im at a loss for what to do next...ill be in TN this summer, should I just drive it from WA to there and have Scotty help me out!
Thanks for all and any advice.
Well I have seen it and at least since it's a standard transmission it's easier to diagnose. From my experience it's generally a fuel starvation problem. I would start by replacing the fuel filter as a clogged one can do that. If that didn't fix it I would pressure test the fuel pump to see if the fuel pump for the fuel pressure regulator had a problem.
Thanks Scotty, ill look into getting the part and getting that done soon.
I called Toyota and even spoke with a technician, they said that "the filter was not serviceable and that it should last the life of the vehicle because its attached to the pump" they wanted around $1,000 for the full fuel pump assembly. Now I'm certain that I want to do this replacement on my own, but thank you for your advice. Just thought I'd let you know.
Also check for an ETCS blown fuse (electronic throttle control system) and the pedal connections. See your owners manual for panel and fuse location.
You may also need to replace the accelerator pedal position sensor, available everywhere, AutoZone, O'Reilly, Rock Auto, etc. There was a factory recall on these but I can't remember which years were covered.
Excellent point, ill check the fuse in the morning. Thanks for you advice.
I checked the fuse and it was still good. I'm thinking maybe I should all the other fuses too just in case. But I will call the dealership it used to serviced at to see if they have any record of the pedal being replaced. Thank you so much. I will keep on trying for solutions.
I had this problem when some oil change shop “fixed” my broken intake tube with electrical tape. It would get sucked in and choke the engine when I hit the gas.
Yikes, would you loose oil because of that? Thankfully, I've repeatedly checked my oil and it hasn't leaked out really much at all and hasn't been depleted since my last change a few hundred miles ago...what did you end up doing for the long term fix for that one?
No it had nothing to do with oil. Except the oil change people tried to do a quick fix. The correct thing was to replace the intake.
