There are actually a few lines in your car. On the hood there should be a diagram of the vacuum system pointing out the different start & end locations. You can take a can of carburetor cleaner from your local autoparts store, attach the long nozzle and just spray a short squirt at a time near the beginning and ending locations of your hoses to see if anything is loose. The engine will slow somewhat for a second or two when the spray is sucked through any vacuum leak. Be careful & only use short bursts of spray along the lines you are testing. Give the spray a few seconds to dissipate/evaporate between sprays to prevent any potential fire hazard. Spray around the throttle body, injectors & the intake also, any leak at all will show with this method. good luck.

Jeep sluggish between 15-18 rpms during shifting from gear to gear. what is the problem


i cant get that slang, DIff , gears, clutch to jibe. 1990 wrangler YJ
what does DONE mean.?
front or rear diff axle new, new transmission? what?
1500 to 1800 rpm 15 is engine stalled, or rpm of oil tanker ship.

got a MANUAL stick or automatic slush pump gear box?
but is no way to answer. you.
its a hydromatic A/T. right>? AUTO?
if yes,it has.
no electronics then. so clean AFT/ levels per operators guide not guessing? hot?
stall test pass (ask)
line pressure tests pass
kick down cable not stuck
or if M/t do say so, mine is, 5 owned..

but we only have one word here, sluggish to work with,
so that can be :
1: engine weak? (low rpms in all gears, and low power)
2: Trans slips (or flares) High rpm and low power (slip)

which is it?, the rpm in each gear answers that.
the FSM shows the range of rpm for each gear. ever seen a real FSM book? factory service manual.

Pajero GDI 3500 with rotation going below 500 rpm and car cuts off


Your car has a bad ground or electrical connection. With electricity especially in cars and more so the older they get. Start at battery and work your way to the end of all ground wires first. Many times i have seen the battery terminals cleaned at battery to terminal connection but the wire to terminal connection are worn or.dirty.look at all.ground from engine to body they often corrode or melt as they are braided aluminum. If all else fails your low idle speed is a vacuum leak listen for a hiss when engine is.running or if u.can seal.the air intake and exhaust pipe.and use compressor to pump air into engine through a vacuum line on intake.manifold keep it.under

Heater vents close and it sounds like blower motor gets louder when passing gear is used


You most likely have a vacuum line leak -- could be in a hose run to the vacuum motors which operate the duct doors or various other places. Vacuum drops off when engine is rapidly accelerated which reduces the vacuum the heating system motors receive. The blower motor seems to get louder because the closing of the doors provides the sound of the motor a different (more open) path to your ears.

Check for vacuum leaks--especially along vacuum hose that goes to transmission or other hoses that connect near the port that the transmission vacuum line connects at the engine intake manifold. Please reply if you have more questions.

Transmission does not shift out of 1st gear automatically. must get off gas for rpms to drop and then it will shift to 2nd gear. no other shifting issues.


There is a vacuum line that is connected to a vacuum modulator on the transmission. The vacuum modulator looks like a tiny inline fuel filter on the right rear of the transmission. Remove the vacuum line from the modulator, if transmission fluid spills out when the rubber hose is removed the modulator is punctured. The engine will **** your transmission fluid through the vacuum line and into the intake system and burn it through combustion. If the modulator is punctured you must have it replaced.

No power in a pull when you are traveling you loose power and it kicks down but looses speed and power when it kicks into passing gear it goes to 4000 rpm no farther and then it looses speed and rpms even...


It could be a number of different things. It could be leak gasket, bad throttle positions sensor, weak fuel pump or just simple as a leaky vacuum line or plugged fuel filter. I would check compression in each cylinder first to rule out gasket leak
