let me start by saying that I LOVE my t-bird.
Best car I've owned.
And I never have any troubles with it.
Okay, there was the time I blew the engine and had to replace it.
And the time the transmission fell apart and I rebuilt it.
And the two times it was hit and needed extensive body and mechanical rebuilding.
And the time the starter went and needed to be replaced.
And the linkage broke and was repaired.
Oh yeah, and the time the throttle cable came apart (scary moment).
But other then that, I have no problems with it at all.
But now, I have a problem.
While on the highway many weeks ago I was at a consistant 60mph, and all of a sudden the car bucked. The RPMs dropped completely off, the lights went dead, and then it all came back up. It was only about a second.
Concerned I took it in that day to be examined.
Nothing was found. I assumed moisture (which is a common problem where I live), in the gas tank, added some HEET dry gas and the car was perfect since.
Well yesterday the problem came back ten fold.
While driving in bumper bumper traffic doing about 20mph the car started stalling. I was pumping the gas to keep RPMs up. It was determined to stall. I had to pump the gas because just pressing it down and holding it (at say what would result in 3000rpms) didn't work. The rpms would go up and come right back down, I had to pump it to keep the rpms bouncing up before it idled down again.
Finally I turned off the road, while turning I didn't pump the gas and it stalled (losing power steering in a turn sucks).
I let it sit a moment and got out to look for obvious issues. Vaccum lines that are off, anything on fire. You know, stuff I couldn't miss (trust me, even after a long day at work, I wouldn't miss an engine fire, I'm pretty savvy that way
Nothing amiss I got in and started it again. It was idling really rough.
More rough that I've experienced in any other car (even diesel!). It was rough as hell, but the rpms were more or less stable. Bouncing between .6 and .9.
So I tried to get back on the road, after about 20 feet the stalling game started again. I managed to keep it running back out to the road (i had pulled into a development). When i pulled out into traffic it was a red light so I was stopping, still fighting like hell to keep the RPMs up. It was then a small puff black cloud went over my sunroof. I looked back and saw a steady stream of black exhaust leaving the tail pipe. I pulled over again and investigated.
Sure enough with the car off it was still leaking out this black exhaust. Smelled like carbon I suppose. It most definately wasn't oil.
The car started again, and I got it to a parking lot. Made some phone calls, and waited. About 5 minutes went by and I started it for a trip around the block.
It ran perfectly. I decided to take it to a local mechanic I know.
On the way there it started bucking again (about 3 times).
After that it was smooth as can be to the mechanic. He found nothing after some quick searching and listening to the car (it was idling smooth at this point).
The rest of the drive home (another 30 minutes) was smooth.
As was the drive in to work today (75 minutes), and the trip out to lunch.
1. The chip (superchip), after 2 years has finally died, and is sending bogus info to the computer resulting in really poor injector misfires.
2. despite the replacing of the fuel filter less then 6 months ago, it could be that.
3. fuel pump?
Before I start replacing and removing things I wanted to get some feedback from those that have helped me in the past, so here I am.
Do my guesses seem logical? And the correct steps?
Or is there something bigger at play here I should be looking at?
And what was that black exhaust?????
