hesitation

I'm getting used to my "new" 1998 UZJ100. JDM import with 72,000 miles. Cosmetically beautiful, and nice, supple hoses, belts, etc. I have a few little projects to address (brake flush, AHC flush) and have already been reminded how excellent this forum is. Driving it in the Colorado foothills...

All, I've been fighting this hesitation since I got it back on the road after years of sitting, '96 was the last time it was registered. Symotoms: Hesitation when engine is colder, get less noticeable when warm, but still definitely there. Feels like someone has a tow strap hooked up and is...

LC200 2013 v8 Starting hesitation - intermittent crank specially when cold started

Was swapping vac lines for new. Maybe 30% done. Suddenly she stumbles taking off in first, when she didn't before. Vac Leak seems most likely. I was banging around alot of those old hoses. Runs okay once there is, a bit of inertia. Any obvious parts of an 82 system I should check for leaks...

Calling all gurus, I have a '94 FZJ80 aussie spec. I've had a problem that Ive been trying to solve for a while but cant get to the bottom of it. I have a hesitation when accelerating from idle to 2000rpm, the best was to describe it is like theres water in the distributor. After 2000rpm, the...

hey guys, so I’ve noticed that I get what seems to be an intermittent hesitation only* under load and light throttle 10-25% throttle, most times I can only feel it lightly surging when the conditions are right however a couple of times it’s very noticeably hesitated and cut out… I’m thinking...

I have a problem when starting, and it's not your typical starting problem. I don't even know how you'd categorize it. I have a 2000 LC100 with 270k miles on it. It starts every time, but recently it's begun to do this thing where when I start it there is a delay of the dash warning lights...

Speedometer bounce is gone. Replaced the speed sensor and not a bounce in a 15 mile test drive. And, a very important side benefit, the transmission hesitation I was also experiencing went away as well. Talked with my Toyota mechanic who indicated that speed sensor signal gets to the...

On a 1998 LX470, are there 2 throttle position sensors? When I search for the TPS parts, I get results for both of these images. I can locate on the truck the one that the throttle cable goes through but haven't found the other sensor. Where is the other sensor located? And, if I am getting...

Hi gang. Here comes a novel, I could sure use some help. 84 60 with a 2FE from an 88. For over a year now I've been getting an intermittent hesitation. When it comes, the more throttle I give it makes it hesitate more. If i back off, it responds as it should. If I keep driving, it will...

I’m requesting wisdom. 1997 year model with supercharger. When I am cruising at 70-80 miles per hour and reach 3-4lbs of boost there is a minor intermittent studder. 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...

Hi All- I wanted to share my recent experience with sorting a trouble code 22 CEL issue I recently experienced with my 91 FJ80 (3FE.) Basic synopsis of symptoms: Extreme idle (2500 on the high side, 300 on the low side) Trouble with cold starts Trouble with hot starts Hesitation on...

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...

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...

Ok boys and girls..here goes. '88 62 with 250k. Has run great for the last 4 years I've had it. Started having some slight hesitation after startup last year but would quickly smooth out. Most recently though it got really bad after having the radiator replaced, front axle rebuild with brakes...

Hey all, Like the title says, whenever I'm cranking up my fj60 (with recently rebuilt engine) I'm hearing a burst of air coming from the engine. Also, when the engine is warm and I'm anywhere about 2000 rpm, the engine starts stuttering/hesitating causing the whole truck to jerk back and...

Alright guys my name is matt ive had my cruiser for a year now no issues when i got it. 167,000 miles all maintenance maintained. Runs 15w40 cold air intake and high flow exhaust. Dual battery So the issue is a get a system too lean code po171 and she runs around 190°f coolant and 90° to 100°...

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...

Followed instructions on valve adjustment and happy with the result. While I was at it; pulled plugs and cleaned, adjusted plug gap to what's stated in Haynes Manual, adjusted points air-gap, cleaned up rotor, adjusted mixture, adjusted idle, and lastly adjusted timing. Rig runs much better...

Hi all, I have seen a lot of posts regarding this issue and very few solutions, so here goes my story / fix on my 1993 LC... Note: This should apply to 1994 and earlier Toyota's with a VAF Meter (not a MAF Sensor). Short Story: Issue: Hesitation / Stumbling whenever (could be cold, hot, city...
