it starts and runs fine, but everywhere you go it has to be pretty much floored and tops at maybe 55ish and takes some time and gotta rev it out to get there in early gears.

Has no power to pull itself up hills..... Timing im sure is close, motor is pretty much fresh, low miles block and lower miles head and new HG and stuff...Carb problems? vaccum lines? Like i said it starts and idles and runs decent, no sputtering or backfiring. But just sucks, Runs good low end, like 1st 2nd, still floor it to go anywhere quick, Its fine when playin in 4wd and stufff since only use lower gears but road ridin sucks *$)

Any ideas before i efi this truck and waste more money.....

it ran better before i blew motor and changed it out....

If it runs ok at low rpms but gets worse as it revs higher, I'd check "flow" related things. Catalytic converter, air filter, fuel filter, etc...
Also check all of your exhaust, maybe you crimped it closed somewhere along the line.

notanymore

i would start with checking the air filter then replacing the fuel filter then look into other things related to high flow, like barnstormer said

i agree with the above, mine gots 236000 and can easily run 75 mph it has no eggs to go up hill and aint going to win no 0 to 60 speed times but it can get you a speeding ticket

yep, that bout covers it. as long as ur sure the engine is fine and stuff uv gotta check out the exhaust and intake. thats where its all at. try throwin in a rly good air filter regardless of what u do. makes a difference in sluggish starts, at least did with my baby. no more pause when i jam it down.

yotanothing

exhaust is fresh, no cat, i put another manifold on when i put it together just recently. Has a round style muffler that wasnt clogged before i put motor back in. Air filter is new, thats all obvisous. Fuel filter i havent checked but doesnt starve for fuel it seems, cuz it goes through it ALOT

check the timing

"runs good no power to it though"

well thats what a 22r does. runs great, no power. do you know the specs of your engine? a 22r i believe only makes around 100 hp. how big are your tires? proper gearing?

it should be able to go faster than 55, thats for sure. i have gone 90 in mine. just takes a while to get there

consider the possibility that your just expecting more power than a 22r has. they are slow trucks, and nothing will make them fast except a bigger motor.

check timing, fuel filter, and all that good stuff. if it runs smooth like you say, then its hard to imagine there's anything wrong with it. what other cars have you driven? what do you have for comparison? because i can tell you man, a 22re pushing a 4x4 toyota is one of the slowest vehicles on the road...it certainly wasn't built for speed

is the throttle cable traveling freely -all the way --opening up the carb 100% ?? and i would replace the fuel filter

yotanothing

i understand they are way underpowered 2.4's. But it used to cruise 70 on highway without being floored on 31" mt's with stock gearing...think its 3.93.

It also diesels sometimes when you shut it off. I checked throttle cable when i first put motor in and was opening up.

Could it be a tooth off on the cam gear? and still start fine and run decent. I know my hondas dont really..But havent had these r motors much.

Just Learning

i have 31 to and can cruise highway with out being floored -just thinking out loud??? distrubitor advancing???? diesels when shutting off > timing??? diesels is also from built up carbon i think, but youv did the heads, so im thinking carb, is it the stock carb dumping in way to much gas running rich you did say its using a lot of gas, i get about 18-20 mpg

Just Learning

also the fuel filter can cause this also, the filter may be clogged up enough so that when you need the extra gas it wont be able to allow it to flow enough, i have had this happen to me , i change filter and walla (it was on my sand rail) but still same thing

yotanothing

people on greatlakes4x4 say cam timing is off a tooth, Which throws off ignition timing also. But said i still could have ignition timing good enough to make it run but not right...To try moving it a tooth either way to see how bad its off....


Could this be true? Will it still start decently and run decently like normal besides the fact you have to have it to floor board to get anywhere within normal driving reasons...Takes more then a mile or roughly that to get to speed limit of 55 which is like floored to floor in 4th gear....havent seen 5th since motor went in.

Gotta rev the ÅÅÅÅ out of it in 1st to go anywhere in 2nd which also has to be floored to floor to make it anywhere when you shift into 3rd. And 3rd i have to take it to almost 55 to get it to stay around 50-55 in 4th, sometimes goes slower in 4th

yotanothing

messed with it for abit today, changed cam timing a tooth in both directions, seemed to be worse then before and messed with changing the ignition timing also while in both changed teeth. So gonna do some more research and see.....

Seems to have some play when you turn the crank pulley bolt before cam gear turns

Anyone know where the notch in the crank pulley has to be for tdc? i know there is a little nub on the back side of the cam gear that lines up with arrow.

yotanothing

since i messed with timing, both cam and ignition.....im leaning to wonder if the vaccum advance on the distributor isnt working? Since it runs decent low end and low gears, wonder if its not advancin the timing correctly and makin it lack power up higher....??????

TNRabbit

That's a possibility. My first question is are you still running 31" tires?

Just Learning

see my thinkig out loud ideas, it may be the dist is it totally flooding out, the accelerator pump on the carb could be bad ?? im not so convienced its timing but im no mechanic

yotanothing

still 31's, had them on there since i bought truck....Ran great before...

TNRabbit

My next guess is vacuum leak (one of my favorite blameitalls!)...but Just Learning had a good suggestion as well. Acclerator pump going bad can dump a lot of fuel in, basically flooding the carb.

yotanothing

How do you tell if the accelarator pump is going out of bad????What would that do?

yotanothing

how would it run if the tdc was on exhaust stroke and not compression stroke??? when i set the dizzy rotor to number 1..
