Recon!
Maniac
This morning at about 0300 I was driving home from work. I took my normal route over some railroad tracks and I hit them at about 40-50, just like I do every day. It's a pretty good hit in a leaf spring 4x4, in my Sierra it's much easier to take. Right after I went over the tracks, the motor started back firing like crazy. Would barely make any power, was bucking all over the place, and would barely idle. Luckily I was only about 1/2 mile from my apartment! When I got into the parking lot, it died and would not restart. I cranked on it and did some magic gas pedal work to get the thing to drive nearly all the way into the parking spot where it promptly died again and would not restart. I had to push it the last few feet, it sucked.
Today I come back for lunch to take a quick peak at it to see if something came disconnected or what not. Everything is attached in it's appropriate place and no wires that I can see are rubbing on anything causing a short. I am a pretty good self mechanic, and this one has me flustered, to say the least. I use the Blazer for DD duties to keep the mileage low on the Sierra, but obviously I can't drive it right now.
I can get it to start, but it requires longer crank times than normal, and it is stumbling and bucking at idle really bad. It surges at probably 200 rpm but constantly wants to die. I can give it a little gas and it tries to smooth out and bring up the rpm's, but it still back fires and stumbles. It is clearly not drivable in it's present state.
The only thing I can think of, is that the timing somehow jumped when I hit the tracks.
I don't have time to pull the cap off the distributer, but I hope I can get home from work at a decent hour today to mess with it.
It's a 1989 Blazer, stock TBI 350 with a throttle body spacer, 700R4 trans. Fuel filter a few months ago, plugs/wires/cap/rotor/coil about 2 weeks ago. When I did all the ignition stuff, it ran better than it ever has in the 6 months I've owned it, but obviously today is a new day.
