lol.. just realized i typed rmp.. once again, im a retard.

 

coils are fine.. I might go pick up that sensor in a bit but i dont think it will help as much as the car needs right now, so i've been focusing more on the fuel and ignition stuff. It kinda seems like its gotten a tiny bit better, but its still just as bad from a dead stop.

 

The IAT helps regulate fuel ratio so if it's giving a false temp reading it might be running too rich which could cause the lack of pressure drop and poor drivability you mentioned. For example, at colder temps you need to run richer than at higher temps so if the IAT is telling the comp that it's colder than it is then you'll run rich. The opposite is true as well, if it's tellin the comp that it's warmer than it is then you'll run too lean. Good luck.

 

yeah, aparently the IAT sensor and the random misfire codes are related, and they can cause each other. Anyway, i replaced the IAT sensor and the check engine light went away, but it's still got a "misfire". But, considering the ses light isnt on i dont think its really a misfire, i think its something with the fuel filter/pump. By filter I mean the one in the tank. I'm almost 100% sure its stock with 131k on it so as soon as i get lower on gas I'm going to check that out and replace it and maybe the pump too, depending on what i find. Anyway i'm not too worried now, i think the misfire is just from a lack of fuel rather than an actual misfire. Once I replace the filter in the tank and the pump I think it'll be just fine, maybe even better than before considering i've replaced the IAT, fuel filter, and plugs/wires.

 

Yeah, I think I'm havin the same problem. I can't complain though, I got 193k+ on the stock fuel pump.

And as far as replacing the fuel pum strainer, in my opinion, if I'm going to go through all the work to get the pump out, I'm changing everything so I don't have to do it again. It's a pretty labor intensive job that I wouldn't wanna do more than once.

 

Hey bill, I had the same problem with my 3.4 94'. Turns out, the coil pack closest to the throttle body, had a crack where the top bolt to the coil was. and, on top of that one of thw two prog things (whre the spark plug wires connect) had rust and wasn't lookin to good. Replaced em, and man, what a diffrence.

 

yeah.. i checked out all my coils and they seemed fine, but i didnt really inspect them a whole lot.
Anyway I'm really wondering before i drop the tank... I think its either an issue with the pump or the filter in the tank. It still has the misfire but it doesnt trigger the ses light, so like i said i dont think its a real misfire, but i think its a lack of fuel. It seems like either the filter is blocked or something is wrong with the pump where it just can't keep up with what the engine is taking in. Does this sound right? Someone.. pete.. anybody.. I really don't want to drop the tank for no reason. Especially since I'll have to do it by myself this weekend and would have to be able to actually get it done by myself.

Also thought about doing this:

but I really don't want to cut it.

 

I did that "trap door" method on my 94 trans am

It was really convient and didn't bother me at all, sealed it up w/ some body filler for easy access in the future...took me about 30min w/ the trap door method after you have the hole cut.

As for the misfire, blinking SES = normally ignition. I would say your coil packs. Visually inspecting them does not mean they are working. Take them off and have them tested at autozone. Clean up the ICM (what the coils mount on) of any corrsion/dirt.

If not the coils I would lean towards fuel injectors.

This is just an opinion but i dont think it's the fuel pump. I didn't get a light when I blew my fuel pump, and mine blew within 5 secs of running out of gas and completely failed, my car wouldn't start at all...so that's why I think it is not the fuel pump IMO

 

well here's the thing.. The ses light was blinking and it came up with a random misfire and IAT sensor. A guy told me that those are related codes, so i replaced the iat sensor and then no more ses light.. So the ses light isnt on anymore, so I was hoping it wasn't something with ignition.. I'll have to check and test those coils again.. but its way better than dropping the tank.

Edit:
Oh yeah and thanks for the help bad.. and everyone else..

 

The "multiple misfire" code is usually the result of lean fuel mixture, or of an ignition part that affects all cylinders. If you have DIS ignition, take a look at the ignition module under the coil packs. Due to the amount of work and cost involved in changing a fuel pump, it would be advisable to change the fuel filter, and then check the fuel pressure under load with a proper F.I. gage, before tackling the fuel pump.
