89 240sx Hesitation
I have a 89 240sx automatic with ka24e engine. The motor was just replaced
with a junkyard motor with 30k miles. Once i got it back, there seemed to
be some hesitation. Off the line, if i dont give it too much gas, it
stutters a bit, but if i give it a decent amount of gas, it seems to be
fine. Also, when i get around 2500 rpm's, the power seems to go away, this
happens all the way up till 3500 rpms. Once past there, it doesnt seem to
have any problems. Does anyone have any suggestions as to what may be the
problem? Thanks

Re: 89 240sx Hesitation
That should simplify it then. Just look at the parts that were kept from
the old motor.

Re: 89 240sx Hesitation
I was thinking it was something other than the motor, since it is the same
thing it was doing with the old motor.

Fuel pump - low pressure.
Engine temp sensor.
Injectors.

Leaks or faults (if flooded with petrol, mixture will go way too rich
as throttle opened) on evap canister purge system.
Inlet duct leaks between MAF and throttle.
Throttle plate and body clean with full throttle plate movement.
MAF - faulty or poor earth in loom.

ECU - check for codes.
Stall while loading - test and check all of the following
Ignition timing
Low idle
Idle air AAC blocked or faulty.
FICD not opnening or full of crud.
Idle switch remaing off.
I've heard lots of cases of people replacing parts at random to fix
faults. A common one is to replace the expensive MAF when the fault
is a poor earth in the loom - 30min max with a soldering iron, the
hard part is finding a technician that can use a volt meter to
diagnose it and an auto electrician to do it. But this is the first
time I have heard of someone replacing the whole engine! Were you
told by a professional mechanic to change the engine? I would advise
you to sue them for the cost of the unnecessary work as it failed to
fix the problem.

The problem with the old engine was leaking injectors. With the dealer
quoting $850 to fix that problem, and another $1000 to install a new timing
chain and guides, i decided to go with a new engine. I found the 30k motor
for 750, and i had a friend install it for me, who charged 250. He's been
workin on cars for years, ase certified and all that junk, and has a badass
Bigfoot Special, so i trust his work. the random replacing of parts might
happen anyway, just so i know everything is new. Either way, i'd like to
fix the problem first, and then just get other stuff as i feel necessary.
