rough idle

Hello, I own a 1993 Hilux Surf SSR-X 2lt-e. I recently replaced the head (big surprise, I know) and now it starts very rough. When I first start it for the day it spews white smoke and idles very roughly for a minute or two. Once it is warmed up it consistently bellows black smoke. I assume...

Hey guys, my idle has been a little rough in my fj80. In park my idle is normal and good at around 650 rpm. When I idle in drive (like at a stop light), however, my idle drops below 600 rpm and sounds really rough. My oil pressure gauge also drops but I figured that was just a normal thing for...

Morning everyone, I have a low idle at 600 rpm, but when the AC is on, I hear a click from the engine bay, and the car idles at about 900rpm. About two minutes later, another click (which sounds like an "off" click), comes from the engine, and the car nearly stalls at 200 rpm until it rises to...

I have been chasing down a lumpy/hiccupy idle on my FZJ80 since I brought it home and I am *almost* done with baselining, at which point I will just accept that's the way it is. My wife has her brand new NX300h in the shop (rodent damage to a wiring harness - don't get me started) and we have a...

1997 FZJ80 - stock 250K total miles 60K miles ago - HG, new head, new everything "upper engine" besides intake/TB Hiccupy idle and running rich. I describe it as hiccupy because it isn't stumbling, low, high, or even shaking the truck. You can only really feel it in your seat, and it's not 100%...

I have a 74 FJ40 that wont run and if I can get it to run it idles really rough and wont let me accelerate to higher rpms without dying or backfiring. It is acting like it jumped time but is that even possible with timing gears? I can turn the crank a significant amount before the rotor in the...

Hello everyone. I started my account about 2 weeks ago when I bought a 1997 FJ80. Drove it home today. It's in decent shape for an upstate NY vehicle... some rust so some light bodywork is in my near-future. 157k miles on it and when I test drove it, it ran extremely well... no issues or flags...

I bought my 1994 FZJ80 about two months ago. Previous owner thought he threw a bearing therefore needed a motor swap. He provided a 'running' replacement 1fz-fe in the price. I knowingly bought it as a project and a learning opportunity. I haven't run into any roadblocks swapping the motors in...

Good day, I have a question about my cel. I have a 94 80 series, with my 02 sensor plugged in I get code 26(running rich) when i unplugged my 02 sensor i only get code 21(oxygen sensor) has anyone gone thru this. I have replaced IAC TPS INTAKE HOSE!!

Hey guys, Long time listener first time caller... Have fuel in my oil, changed oil ~1000 miles ago and now oil is above full line (was below for several days before commuting for a week) Seen a few people post about this but no real resolution. Some say leaky injector, some say PCV valve is...

For the last month my 80 has been shifting a little slower, I didn't think much of it since the 80s aren't known for their fast shifting, but yesterday, I put my car in park and left the AC running while I was waiting for someone. About 10 minutes of keeping the car in park the RPMs started...

Hello, I recently got a '92 FJ80 and have been working out the kinks to get to run better. The truck was bought with a broken ignition cable for the 6th cylinder. I have replaced spark plugs, cables, distributor cap and rotor. The engine was still idling rough and at low RPM after that so I was...

Hey people! Problem with my 94 fj80. If I'm on the back roads keeping it under around 30mph it wont happen, but after I've hit the freeway and coming to the stop light, it always rough idles, sometimes dies. Happens almost everytime I've been driving high speed. I'll put it in park, hit the gas...

Earlier this year I acquired (paid too much for) a 78 Fj40 and began a DIY restoration. I was fortunate to have found a truck that was 100% original and have enjoyed resurrecting my 1970's mechanical intuitions. The main difference between 1970 and now is that its much more difficult to slide...

Hi Team: I'm kind of a newb to working on rigs, so hoping for some guidance from the experts on what I should check on my '93 FZJ80. I'm experiencing a rough idle and rough engine under load. It also feels like I'm down a bit of power, but I can swear by that claim. I'm not throwing any CEL...

I pulled into the driveway today and my car was running rough. Fine all the way home other than that. I rev the engine and the CEL comes on. Check the code and it says there is a misfire in cylinder #1. I can smell gas or rich exhaust in car. Pop hood while it is running and see exhaust...

Hi Everyone: I'm having trouble with a rough idle when my '93 FZJ80 is in gear. I initially thought it was a bad IAC, so I pulled the sucker out (which is a massive pain) and tried testing the unit by hooking it up to my battery via alligator clips and following the FSM test guide. Low and...

I got a starting and idling issue on my 91 land cruiser. It will start with no problem in the morning when the car is cold. It usually takes 6-8 cranks to start. It will took 15-16 cranks when the temperature is high. I can feel some misfire when the car is idling, but it will never stall. It...

1hz motor in my 80 has a really rough/odd idle behaviour where it feels like one injector randomly doesn't fire at random intervals. The injector pump and injectors were replaced about 6 yrs ago. Never been touched since. I could replace injectors with a full set of brand new ones myself but I'm...

After having recently installed a number of things, I am trying to diagnose what the F is up with my FJ62 truck. First, what I have done recently. Over the last two months the truck was out of commission. I replaced the side cover gasket ( which meant that I took out the distributor, air...
