I have a US spec '82, that has something wrong with it. I am tired of Geo's being able to beat me off the line... I had the fuel distributor replaced last April, due to a bad master cylinder leaking brake fluid into vacuum lines, and ending up in the fuel system...ever since then, the car has not been quite rite... anyway, coming off idel, there is a lot of hesitation, then it will start to creap away, it will usually backfire into the intake, then pick up speed... I pesonally think that it is flooding the system, then the computer leans out the mixture, hence the backfire, then the car will run.... I have recently had the timing adjusted, things only got worse, and the CO mixture adjusted (not real sure what they meant by that) It is my understanding that you need special tools to adjust the mixtures....any ideas will be appreciated

When you say leaking into the fuel system, you mean? There is no way it can leak into the fuel distributor. The vacum management can possibly see some contanimation, but that would be such a rare situation, the vacum from the booster is higher than any leaking fluid level. I might be able to pull some residue from the vacum action but I would think at that point you would have no brakes what soever due to the amount of fluid loss. Of course you wouldn't have any power assist either. But just for the sake of science , post as much as you know and where/who the problem/solution was determined. It sounds to me that you might have had a fast one pulled on you by the shop!

Well, I'd have to agree that things sound pretty screwed up with this car. I'd first try checking the part number on the newly installed fuel distributor, make sure it's the right type.
Then I'd check the timing belt, make sure it's set properly, and properly tensioned... then new fuel and air filters... then new plugs, check wires, cap and rotor, and ignition timing setting... then ensure no vacuum leaks anywhere in the system... then a closer look at the fuel injection, clean the injectors, etc.

Yeah, I know, that's about everything you can check - for a reason! That's the list of everything you can check, pretty much in order of increasing cost and complexity. You really should go through the whole system, as much of this stuff can be thrown out of whack by a bad mechanic. Sound like you should also perhaps get a Haynes manual and do some reading, start learning about your car...

When I got the car, the previous butcher...I mean "owner" told me it had a brake fluid leak, but didn't know where it was. After putting much fluid in over the next few weeks, and not finding where the fluid was going, I noticed that the car started doing its impersonation of a crop duster just about the time to put more fluid in...I would lose pedal pressure. I decided to put a new master cylinder on after a few days. When I pulled the old one off, I found the vacuum assist FULL of the vanishing fluid. Apparently, after several months of this cycle...fluid passing by the seals, into the vacuum assist, refilling with fluid, pumping it out.....it built up enough fluid to make its way into the fuel system. Since I am the one who found the fluid, I know that no one is pulling a fast one on me.

Well, I did find the timing (valve, not ignition) wasn't quite right, it was off a tooth. I put a new belt on, and the car is running much better, except for an annoying whine, the sound of a power steering pump low on fluid almost, but much quieter. Some not too bright wrench jockey tells me that it may be due to the new belt, and might go away shortly. I readjusted the belt to make sure that it wasn't too tight. Now the car runs much, much better, but still isn't quite right. If I ever find the dang timing (ignition, not valve) marks on the old flywheel, I will set it. The caps, plugs, wires, rotor, and filters are all new.
