99LexusEs300 seem2sometimes stick at3-4000 RPM when reach60+Mph just started happening this week any ideas?boughtcar 5months ago 241,000miles havenot yet done transmissionflush beencold outside 30-40°

when did it last run good, last week, last year or nobody knows/
that is good one, odd for sure that. NO scan tools work 1995 ,
2.4L stick shift. M/T
well the engine has no idea at all what gear you are in.
so my guess is, yes engine is overloading, (reverse is better )
means engine power is super super weak.
because REV has a higher numerical RATIO gear. than 1st.
so seem have more power. in REV.
sputters up is not a norm car term, but can me 2 things

• gross engine misfire.
• or the clutch slips. (RPM Rises but MPH goes slower.?

the engine dies/ DEAD, 0 RPM? that be>>>>
MY BEST GUESS BLIND, IS ENGINE IS:

• ENGINE IS FLOODING , SMELL FUEL? injector leaks.
• SPARK IS BAD,
• OR FUEL FLOW LOSS. LEAN BURN STALLS.
• Bad fuel, (old fuel was there before or now?).

there are lots of actual caused (parts bad)
spark parts all are old aND NO GOOD NOW. PLUGS/WIRES HV,CAP ROTOR HAS DISTRIBUTOR? YES IT IS.
BAD FUEL OR LOW FUEL PRESSURE OR CLOGGED FUEL OR AIR FILTERS.
all above assumes actual engine is ok, compression tests pass.
that is all I can figure out , not seen or driven me.
I can no see RPM and MPH dials or hear the engine sputter.

Sounds like a bad t-stat. Is the heater output low?

I understand that driving means pressing the gas-pedal....

Remove the battery cable & see if it will relearn the shift points

I doubt a 1992 even has that capability,you may have a failed trans

randomly will not start 3 times?????? Won't start how ? When you turn the key to start ,nothing happens or the starter engages an spins the engine but won't start an run ?

Replace your dead alternator.

well your tranny is slipping check your tranny fluid make sure its not low on fluid

That is normal,If you do the same speed in 4th gear the rpm's will almost double.

The rpm's will repond faster in a manual than an automatic.

In a manual the engine supplies the power required directly to the gear that you have selected thus the engine rpm's will increase or decrease as needed.

Have the test run and deal with what shows up, keep your fingers crossed that maybe it is a cheap fix, but as a 30 year veteran of new car dealer repair shops quick fixes are few and far between, I hope you have good luck and yours is an easy one.

car out of cruise control flutters or runs rough from 45 mph to 55 mph and once over 55 mph runs smooth. I notice from 45 to 55 the rpm guage moves with flutter or rough running engine. when i put in cruise control it smooths out.
