Chevy TrailBlazer Loss of power
I'm a computer admin with some mechanics experience from working on Ninja 900cc..can do maintenance but not much of a troubleshooter when it comes to cars
I started noticing that once in a while i'd be driving in the range of 20-65m/h and have no power regardless how I push the gas pedal. Engine runs but tranny doesn't get invloved. I'd release the pedal and just roll for a couple of sec and push again and it'd be fine.
well, it's been over a yr now, and i find it doing it almost every time I drive it. it happens when engine is cold and when it's at normal op temp (I'm in Dallas, car warms up very fast). Most of the time it happens on the ramp getting on the highway and speeding up on the hightway but mostly in that range.
I haven't had any warning lights come on or engine lights... starts everytime, even in the winter. I change oil myself every 3,500 (Castrol GTX 5w30 with AcDelco filter). Tranny oil is still from the factory.
so one day it wouldn't pull while going up a steep ramp and tried releasing and pushing the gas pedal as always but the engine just died. I was able to pull over to the shoulder... switched to neutral and SOB started just fine!
I tried scanning the computer, but the scanner can't seem to establish a connection (keeps telling me to plugin the cable).
I'll take the dash apart this week to check if I forgot to connect the OBDII jack back after I run the fog light switch from the dash into fusebox.
Some guys were mentioning bad Neutral gear switch .. can I test that in some way or only a dealer can do that (where is it anyways)? Is it possible that I cause the problem by resting my right hand on the gear selector while driving?
Since the car didn't have warranty I made following upgrades after I got it: replaced the stock stereo with a mp3/USB deck (had to buy special harness with a chip) and installed a pair of fog lights with harness (7A on the same fuse as RPM gage, only I replaced 5A rpm fuse for a splitter with 2 5A fuses)
Thanx so much in advance for any ideas and advice.
