Damn car......Need help!!

[HyBird]

Ok well let me start from the begining! I have and '89 firebird with an L03(305 TBI) and 700R4. We got the car, and it was running pretty well, although it would heat up to 240-250 when you would drive it due to the fact that the coolant needed changing and there was no airdam. My brother drove it like this for a week or two. Well one day he told me that he couldn't get the car started. So I went down to his high school and checked it out, got it started, but it was running like a piece of crap. Only about half as much power as it should have, and when it idled in park it would surge, like go from 700RPM to like 100, almost die and then come back up to 700rpm. Well we took it home, changed the fuel filter, checked the plug wires, changed the map sensor, EGR valve. That helped a little. Well I noticed that the fuel injectors weren't acting right. They were just pissing fuel, not the good conical shape they should be spraying in. Well at the time my bro could not afford new injectors, so he drove it like this. After a while the car started running even crappier. We found out that after the car was turned off the injectors would continue to leak fuel into the throttle body, and when the car was started it would take forever to get it going, like you would have to clear the excess fuel out of the engine. This unfourtnately led to the oil getting thinned with gas, and eventually oil started coming out of the tailpipe! So yesterday I got a whole throttle body with injectors, and put it on. It started it up after putting it on, and the injectors are fine, but the car still runs like horseshit! It surges at idle, you can only give it 1/4 to 1/2 throttle from a standstill or it stalls and doesn't go anywhere. Even when giving it that small amount of throttle it tries to stall, it has no top end power at all. You can kind of hear the car missing too. I really hope someone could help me with this, I have no fuckin clue where to go from here, and I am starting to hate the firebird! <img src="frown.gif" border="0"> <img src="mad.gif" border="0"> <img src="mad.gif" border="0">

since your bro kept warming the car up and cooling it down, check your headgasket on one of the banks. having the car at hi temps would warm your head, and result in a blown gasket. if a blown gasket is that case, im sure there will be some oil in your coolant or coolant in your oil. also your idle will bounce up and down if you dont have enough coolant in the car.

changed the oil twice now, no coolant in the oil that I can tell, but it was full of gas?! WTF does that mean? Although both occurances of this were while the car still had injectors that leaked like a sumbitch when the car was not running, now that we fixed that problem with new throttle body and injectors, it has been allright.
