1991 Firebird Ignition Problems

I have a 1991 Firebird and it has 220,000 miles on it. V-6.

At random times the car won't start right away. I have to keep turning the ignition to get it to choke and turn over. It usually does after about 20 minutes of trying. If I let it sit it'll start right up (like overnight). But 2 days ago I took it in to get a new muffler and it started fine when I took it in, and when the guy drove it in the shop. When I got back, he said the car wasn't starting and that he looked at the engine and noticed it was flooding itself whenever he tried to start. He took the fuel injectors off for a moment, and it'd start and burn the fuel it had in it, then die. Once he plugged them back in however, he claimed it would not start.

I've been going out there trying to start it, and if it does start, it's a really heavy start. To be more descriptive, instead of a vroom vroom, its more like a doonk doonk doonk doonk, with the engine shaking really bad. That was yesterday. Today it will not even do that. It won't turn over at all, and there IS an oil leak, albeit a minor one.

I really need to get this car into working order. Any ideas as to what the problem could be? Thanks ahead of time.

It sounds like your injectors or either clogged or partially clogged. I could be only one or two of them are clogged. It's too expensive to have them cleaned so try running some fuel injector cleaner through your fuel system a couple of times. That should clean them out and help the car to start and run better. If this doesn't work, you may have to spring for the injectors to be clean or replaced professionally.

Hope this helps.
