I have noticed my truck was a bit harder to start the last few times when
going anywhere but tonight it started running real rough. If I gave it any
gas at all it would slow down and start shakeing, if I took my foot off the
gas pedal it would speed back up to aroudn idel speed and start moving. It
would then speed up and slow down like someone was pressing and releasing
the gas pedal.
I was able to crawl home that way and when I got to a stop light I shifted
to N and the engine speed started climbing till the light turned green so I
dropped it in D and chirped the tires and sped off. When I pulled in the
driveway it was like I was standing on both the gas and brake. It hasn't
set a SES light yet so I first thought maybe my fuel pump was failing until
the engine speed started to climb. TPS maybe sending back wrong position?
Around 50k it was running a bit rough so I replaced the plugs and wires
with Ac delco and changed the fuel fillter. I have about 63k now, its a
2000 S-10 2.2L. Does TPS sound reasonable, since I have no SES light I
can't go anywhere to have any codes pulled.
