ok so when accelerating, my car bogs so bad....like it will feel like the car just completely loses power, regains it, then loses it, it doesnt do this when the car is cold, and maybe like every 5th stop light, it wont do it....ive changed fuel filter, spark plugs, wires, distributer....what could it be?

timing? injectors? anybody help im so frustrated haha...and it did this before i was turbo so i know its got nothing to do with that

 

anybody?

 

Check timing, leaking wires, o2 sensor, coil, ignitor. Swap out distros to isolate the coil and ignitor. I had that same problem and i bought a new O2 sensor from groupbuycenter.com, NGK.

 

If you've done all that I'm leaning toward o2 sensor too.

 

try tps sensor, they do that when they are bad or dirty, also clean the ivac? i forgot the name but its on the back of the manifold. simple things to try to help you out.

 

ill have to try these, thanks a lot, ive been told its probably my timing, any more suggestions would be helpful, thank yall

 

I had the same problem. I just replaced the cap, rotors, wires, plugs, and ignitor coils. Bog was %100 gone.

 

how much were the coils

 

changed map sensor, no luck

 

What about the sock on the fuel pump.

 

you know what? honestly, it'll be cheaper to just take it to a dealership and have them diagnose and fix the problem than to parts-swap.

dealer - $115 to diagnose, then the cost of the part to fix the problem

parts swap - $$$ to replace the fuel filter/pump, fpr, distributor, coil, igniter, tps, map, o2, ect, iat, etc... there's just too many things that can cause those symptoms. (actually, some i listed really aren't your problem, but someone is going to, or has, suggested). unless you have a multimeter, and/or vacuum pump, scan tool to diagnose, it's not worth it to swap parts.

 

ok i think im gonna replace the whole dizzy, ive been reading and the distributor has caused the hesitation like i am having

 

Poke and hope. Good luck.

 

Here's a little something.. You said it doesn't do this when the car is cold.. So that must mean that the ECU hasn't started to adjust air/fuel ratios according to the O2 sensors..

What I would to is plug a Scan Tool into the vehicle and watch the O2 sensor and see how fast they're responding and continue diagnosing from there..

 

Do your revs drop when this happens? Because if not it could be your clutch slipping. The clutch on my lude is like then when I first drive it on a cold day. I will slip/catch/slip catch for alittle while. Then it is fine...maybe it is the other way around and your clutch is hot? Because it will slip when its hot too.

 

i know what a slipping clutch feels like and this is def. not my clutch

 

then..i am agreeing with pnx..check your O2 .and if thats not it. Then for gods sake bring your car to a dealership.

 

timing was a little off but nothing major, fixed it and nothing, im gonna do o2

 

I had a problem like this a few months ago.. Mine was from my fuel pressure. What fuel pump and FPR are you using? Also is your fuel line to the rail modified at all?

Do you have a fuel pressure gauge? I had trouble getting my fuel pressure down with a B&M FPR when I installed my Walbro 255.

I had the same problem with my Holley pump. Made it run rich.

 

it has nothing to do with my fuel pump because it did it when i had the stock one in.

 

Did you swap the dizzy yet? If not get another o2 in there. Or get a voltmeter and check to see if the voltage off the o2 is within specs. I did that and saw that my o2 was responing slowly. Good luck.

 

do you have a smell of gas? or anything like that... i had the same problem but mine was from a faulty vafc.

you might be running really rich. probly not your problem but wouldnt hurt to check out.
