I finaly took it in the woods was running great plenty power. Motor did fantastic then i hit some bumps to fast and hard. It started running ruff . I got spark and all that good stuff. I was wondering what u think the chance are of some junk in the fuel tank came lose and cloged the new fuel filter. ANd or i took my dizzy cap off and it sorta looks like it has some hair line cracks in the top. but they sorta look like mold lines. im not shore. could a bump be enuf to hair line crack a dizzy cap?

Its blowingmymind cant find any vacum lines off no plugs undone. all plugs and wires are on and geting spark. what could i have done?
 
The dirt in the tank being stirred up sounds reasonable to me, especially if it sat for a while before wheeling. You can check the pickup screen in the tank really easily through the panel under the rear seat. The gas filter is on the pass. Side of the block.
 
i did discover if i tap on the front of the intake manifold where the butterfly is . if i tap useing like a ratchet it will make it stall out. but i will check the tps when i go back out. Its running like it has a real bad misfire. almost but not as bad as when it had cloged injectors. mr injector cleaned them. and it had new fuel filter put on. Hope its the tps
 
Check the air duct that runs from the filter to the intake. Check that the clamps on each end are tight, and especially look at the flexible elbow right by the intake - they tend to crack down inside the low spots. Any air getting into that tube is not being measured by the MAF, so the EFI control is not accounting for it and you will run way too lean.

I coated mine with "liquid electrical tape" which seems to be holding up OK (for the last couple of months, anyway.)

Good luck.
 
yeah plug wires are fine not only do they have less then 400 miles on them i slid my hands up and down them while running. with one hand and had my other on the intake. If they were shorting i should have got shocked. I unhooked my TPS it didnt change how it runs. had the exact same rough idle and hesitation as it does hooked up. think its my tps?
IM still learning on the toyotas. this is my second yota first was fj62 with 3fe.

thats what i had unpluged as tps. Im corect in thats the sensor right? On the yotas is there a way to clean them or do i just gota suck it up and go buy new one.
 
when it started running ruff sunday. i was looking for the problem and was taping on front of the intake manifold in the area of the tps and it made the truck stall.
 
well went pepboys. looked at new dizzy cap it had same lines in it as mine so i figure there molding lines got replaced fuel filter didnt fix the problem
 
okey dokey. i replaced. THe fuel filter. and plug wires. also the front hose on top of valve cove that goes to intake manifold i replaced it. runing better now. but still has whats acting like a missfire. Could the gasket that goes between the downpipe and the exhuast manifold leaking cause this on a 22re? this is my first 22re and only my second yota so i dont no how these things afect them. On a chevy it just gets louder so im not shore.
 
also didnt have this problem till i adjusted my idle. COuld the tps cause a hesitation? Like i lost a cyl almost

Hello I was wondering if the rough idle goes away after the motor is warm? Is it affected when you stab the throttle for a moment- what does it do after?

Also you could check that the egr valve on top of the valve cover is operating properly. Sometimes the ball inside gets stuck.

I don't know a lot about tuning/motor stuff but own a 22re and have had others.

My 22re modified sometimes has a rough idle if started cold and sometimes when it rains. I have found a bit of water under the cap/rotor even when I have not driven the truck hard/offroad/in water.

The cheapo cap and rotors these days need change out often.

Keep me posted- I'd love to hear what you find out

its 25 degrees out right now. little to cold for me go out and mess with it. At this time anyway. How do i test the mass airflow. or what am i looking for? i took my dizzy cap off it was dry inside and clean. WHen it started running like crap it had been ran for a couple hours by the time i hit the bumps that made it run like shyt. It almost idles corect but u can see it haveing a stumble it use to sit there and idle smooth enuf to sit ur soda on top without it falling off. WOuldnt try it right now. When i go out i will remove the pcv and squirt it out with some card choke cleaner see if it helps. WHen i give it gas it stumbles then trys to smooth out but it never get the power it had befor this issue.
 
There is a detailed procedure in the FSM for the MAF on top of the airbox. You'll need a DVM, you can just unhook it and bring it inside to do the testing.

This still sounds like a cracked intake hose to me. The elbows get brittle when they are old, and cracks can be hard to spot. Bring it inside, get it warm, then shine a flashlight thru the elbows while you gently flex it, see if you can see any light coming through.

When was the last time you did a valve adjustment? Checked the timing?
 
havent done valve adjustment. and the timing belt or chain what ever it has was done when the motor was put in. I didnt have any issues till i hit some bumps real hard.
 
you can test for exhaust leaks by adding a little sea foam to the intake. follow the smoke trail. that's how i found my leak at the manifold doughnut.

just wondering, did you hook up all the grounds back to stock locations?

still weird that you can stall the engine while tapping on the intake manifold.
 
i actualy replaced 1 ground and added a second ground ones from the body to the motor other is abttery to the motor
