1997 S10 Problem

[reckedracing]

So my friends truck died yesterday under normal drivig condition...

138K on the clock

4 cyl, 2.2, 5 speed chevy shitbox

it has no throttle response, horrible misfiring, you have to hold the pedal to the floor to get it to start/idle, pedal on the floor does not make it rev

we've tried the following:
crank sensor
coil packs
ignition module
exhaust/clogged cat
fuel filter
computer
map sensor
tps sensor
iac
plugs
wires
compression test, all cylinders good
checked rocker arms/valve train

we had all these parts laying around from doing my truck and it still runs exactly the same, its baffling

drop the 4.3 in it....

 

[reckedracing]

i'm ashamed of you...
small block or leave it stock...

vortec junk
i hate those motors...
they toss rods like ron jeremy in his golden years...

we should drop a 302 in it and really fuck with the chevy lovers

 

[BodyDroppedNikes]

lol

in all seriousness tho, have you checked the throttle cable to see if thats came loose?

 

[reckedracing]

yea, throttle cable is intact...

its the fucking strangest thing in the world...

it just doesn't make any sense

keep the ideas coming though

4 cyl s10 tickers are KNOWN for HG leaks...

Might want to look into that.

Heh, I had the exact same truck... '97 s10, 2.2L, 5spd... and right about 135k it started doing the exact same thing! I couldn't figure out wtf it was either, I sold it for $700... total piece of shit.

 

[reckedracing]

it was the timing chain, it was fucked
motor runs great now
