She is doing it again!!!!!!

[djcaz_aom]

I'm having the same problem once again.

I posted a thread on my CB loosing power, and everyone helped out.

She is doing it again.

- After highway driving, the car will loose power between 1500-3000.
- After warming up, the same thing. It will backfire even at times.
- If I let off the gas, and press the gas again, it sometimes clears up; sometimes I have to pump the gas pedal to get it to operate normal again.
- As soon as it reaches 3000, it feels like a booster kicks in and away she goes.
- I even unpluged the EGR, thinking it may be clogged and that didn't cure it.

Before you start calling things out here is what I have done:

- New spark plugs and wires-
- New rotor and cap
- New fuel filter
- Fuel injectors replaced
- EGR replaced
- EGR ports cleaned
- Switched fuel brands.

Alright. Now move on to your vacuum lines, your intake manifold gasket,
With the engine running get some carb cleaner and spray a mist around the vacuum lines,intake gasket and throttle body gasket. If the engine surges, then you have found the problem . if not


Check your fuel pressure with a fuel gauge between the regulator and filter, then check your regulator itself and pump. Everything checks out there, ignition timing. no check engine light I take it?

No check engine light. I also replaced the O2 sensor, Fuel pressure regulator.

Be back in a sec; going to do the above test.

I did the leak test and nothing. I will check the fuel pressure next.

Hows the trans holdin up? This is in all gears right?

try looking at the ignitor when it starts to go it will cause some of those problems

ok.....Is it running rich at all?

Sounds like its getting too much fuel.

Check ignition timing

check your throttle cable also.

The resistance on your ignition coil

Can you smell rotten eggs when your windows are rolled down? After you've driven your car for a while, get under and look at the cat with the car running. If its smoking or cherry red that right there is the culprit.

i was gonna say maybe the ignitor too

Tranny is holding and it does it in all gears.

I'll replace the igniter and check the resistance on the coil in the morning.

Thanks everyone.
