Question about 1983 Toyota Pickup

1982 Toyota 4x4 22r wants to run hot at highway speeds

It doesnt get into the red but close to it. Also the timing was retarded and we corrected that. But, it doesnt run as hot as it did and the heater does not put out hot air. It is only warm air. I changed out the thermostat last week and it has a new radiator. Could the heater core be stopped up cuasing all of the troubles? It is the original core and the truck has 279,000 miles on it. Thanks

    over the last week there have been a couple times I've noticed cool air coming out of heater vent when car was adequately warmed up. This improved with increasing the temp control from 69 to 74 or higher. 80,000 miles on it

Seems like air in system problem, park the car such that the radiator is the highest point of the car, can also use jacks, put the heater in the car on, run the car with radiator cap open til theres hot air coming throung the heater,make sure radiator is full.

Husq 125b starts great! & runs 5 min, exhaust glows cherry red hot and engine is now at 50% or less power. Exhaust is not clogged; fuel ratio is correct....???? :(


ignition timing is incorrect or valve timing (if 4 stroke) is off
ignition timing is too far retarded and if 4 stroke , the exhaust valve is staying open too long ( tappet clearance )
the indications are that there is compression flame escaping into the exhaust when it should be out

Why is my crown vic slow and hot?


I would say your exhaust converter is worn out & blocking
the exhaust from getting out & since you continued to wonder ,
verses actually having the car tested,that you now have ruined the transmission

Idle problem


what engine? # cylinders , displacement.????????????

ok, the EFI is in charge of idle speed at all times.

low speed ,usually means the EGR is stuck wide open

the main valve. clean it ever 50k and no more.

ill list some other common, ways, (not guessing, i do tests)

1: EGR stuck.

2: someone set the ignition timing way retarded

3: the cam timing is way retarded. (zero service caused)

4: flooding,

5: starving for fuel.

6: ISC valve stuck closed.

7: horrid need of a basic tuneup. 60k mile full service scheduled parts.

How to adjust idle?


hot engine ?, cold or both,, EFI runs in 3 modes, cold ,warm and hot.

name it.

which engine option (displacement)??????



there is no idle adjust, that is the PCMs, job 100%, all the time.

Carbs are gone.

here is rule one for all EFI.

idle is the last thing to work correctly.

anything the causes a gross imbalance of engine power to engine load, under idle will cause , idle controls to fail.



low idling causes. (over 50 but, here ar basics)

1: AFR (air fuel mixture too lean) usually surges. (clogged or leaking injectors. or fuel pressure way to high)

2: air leaks, cause racing, so not that. (speed density car ,if is)

3: egr stuck open. low idle and misfire.

4: ISC stuck closed (IAC electric)

5: cam belt slipped, timing retarded, compression at 1/2 spec, and well, valve will bend soon....

6: CEL glowing running? can be in limphome, limp cancels Idle controls (in may cases) RTM read the FSM on DTCs.



if fails hot?, is hot = 180F temp or more? "thermometer time"

if not, the PCM goes , quite nuts.

If running ok at idle and not running hot, then I'd first examine my rad hoses very carefully, especially lower rad hose. If old and soft, easy to squeeze then replace it/them. Also replace rad cap as well. A soft hose may be collapsing when engine RPM increases, and restricting flow through engine. Next would be to observe water flow with engine running to be sure water pump is doing it's job. I assume you have cleaned and checked rad already. Note: if you run at highway speeds and it gets hot, try turning heater on high fan and hot setting to see if temperature gauge goes down at all, which would make me lean toward a faulty radiator.

Hi. I have an '82 F-150 with a 351 c.i. engine, the extended cab version with the full-length bed, 4WD, with only 20,000 miles on it. When I'm driving about 70 mph, the tachometer reads 3000 rpm, which...


Hi

It does look like you have a 3 speed C6, if the PRND21 description is correct. If you do have overdrive, the "D" will be printed in a white oval.

Sounds like it is OK. My Mustang has a 351C with a C6 trans, and 3000 rpm is about right at 70mph.

The defining factor on the rpm will be the Differential gears, which in a truck, might very well be taller gears instead of highway gears, as the taller gears provide more power output at the axles than the highway gears do.

Example:
if you had 3.0 to 1 gears (Highway), that means that the driveshaft will turn 3 times for every complete revolution of the rear wheels(Axle)

If you had 4.0 to 1 gears, then the driveshaft would turn 4 times for every revolution if the axle. Lots of torque for pulling stumps, but on the highway. the engine will have to turn more rpm's to maintain 70 mph vs a 3 to 1.

with the 3 to 1, you will turn less rpm's on the highway, but will have less available low speed power (Torque) at the wheels.

Sounds like the truck is doing fine.

level surface, vehicle transmission hot, selector in park, vehicle not running---check dipstick level to be within hash mark lines. Look for orange/red color, and smell dipstick to ascertain a "burnt" odor.

If color is not orangew/red, fluid smells "burnt", and level is low, BE$ CAREFUL!

Plug or restricted catalitic converter, removing the o2 sensor and installing a back pressure gauge will verify.

It needs a "drive cycle". Start & run it, highway speeds, and then pull over & idle several times, then do city traffic "stop & go" driving, and then sustained highway speeds again. This completes the readiness thest and satisfys all of the monitors.
