sluggish at low RPM

TheMetro · 06-20-2008, 01:04 AM

I bought a 91 LX with the 4cyl. It is very sluggish/unresponcive at low RPM (below 2000rpm) once it gets past 2000 it feels and revs like I would expect it too.
What would any of you recomend I look into first, to get it running normal ?

actually that sounds normal for a 2.3[8D]

Agreed, it sounds normal. But try a tune up if your worried

a tune up never hurts.

plugs
wires
fuel filter
air filter

clean maf, iac, tps
oil change

and it will be running like brand new... not much of a difference tho[8D]

After a tune up,(assumeing I getbetter responce) what would be thebest modification to get fast/solid throttle responce ?

2.3 turbo
5.0 swap
351 swap

or be different.

2.9L swap
3.0L swap
4.9L I6 swap

the 2.3L NA engine has no potential whatsoever, without any amount of money.

if you want faster throttle response. look into lighter pistons, rods, a lighter crank, billet flywheel, ligheter clutch.

Good luck on a lighter crank, the forged ones weight more than the cast[&:]

gut your silencer, or add a CAI to get a little better response and add a header and exhaust

Seafoam!! it needs to be added to the list of things to do during a tune-up...or right before.

Welcome to the forums

OK thanks for your help; Here's how I see it,1st seafoam,then tune. But after that(when I switch this engine into it's new home). I plan to rebuild/refresh the longblock and addK&N cold air,Headers,Lg.exhaust(no cat.),remove unessary drag(PS pump etc...,where it's going don't need one)underdrive pullies,I'l trysome simple porting myself,Lightened flywheel,Aluminum driveshaft,remove the air silencer & EGR system. Thats about it budjet wise.
Any thoughts on my plans so far would be appreciated.

Your wasting money on a 2.3 that may run a 16 1/4[:@]
