It only lasts a second and might only happen 2-3 times. I’m wondering if anyone has some insight. It feels like a miss. I put a...

    Hesitation & anti-diesel solenoid

    Been wrestling with a major hesitation situation with my 71 FJ40. Been floundering around for over a month. Truck idles great, and once you get past a massive flat spot it runs great again. But there is a 'dead zone' between (roughly) 1200 and 1800 rpm. If you let the gas pedal linger in this...

    2001 Corolla stalling, hesitation

    Just gonna post this up here, so maybe i can find it again later. This is a software problem, a firmware update could fix, but they will not roll it out. This throws O2 sensor codes, and then cyl codes as vehicle starts to misfire. Simple fix is to disconnect both O2 sensors in front of cat...

    91 3FE Hesitation & Stumble

    Hi, I'm experiencing hesitation at low speeds, clears up in 2nd & 3rd, then at high speeds it stumbles when dropping into 4th gear. My idle is a bit high in park, and drops to 650 in gear. At a stoplight, in gear, it stumbles. Could this be a fuel issue? A buddy of mine swears it's the fuel...

    AHC Quick Question on purchase

    I am looking a purchase of used GX and the AHC works but has a hesitation when going up and down. It will move up, hesitate a little and then sort of a little clunk before continuing to go up. Is this normal or a sign of future problems? Thanks in advance for your thoughts.
