Engine loss of power?

Engine?
Miles?
Manual / AT?

Let us Know on the info.

Hello !

Start checking the TPS (check the voltage with the wide open throtle)
Then the EGR for carbon build-up (clean it)

And the Maf sensor.

The Mass Air Flow sensor is crucial to the fuel systems operation. This is the sensor that the engine computer uses to measure how much air is entering the engine so that it may properly deliver the proper amount of fuel. A dirty MAF sensor hot wire may cause several problems to include: difficult start, poor acceleration, pinging, rough idling, to name a few. This whole procedure should take you less than ten minutes.

Its the check engine light on?

Check them and get back with the results.

I`l get some info on the how to and I`ll post it later if you don`t know how to test the sensors.

BTW I saw that you donate!
Thanks a lot! We appreciate that!

Good Luck!

Hey Kevin!
In this case your car uses a MAP sensor (Manifold Absolute Pressure)

a MAP sensor simply compares the pressure difference between 2 chambers. One chamber is sealed and used as the reference pressure (usually a vacuum) and the other chamber is connected to the intake manifold (usually by a vacuum hose). When the pressure in the intake manifold changes, this will change the voltage signal going back to the ecu from the MAP. A pressure drop will cause a voltage drop. This voltage is only interpreted as manifold pressure. The ecu will also need to use the signals from the rpm sensor and air temp sensor to calculate air mass, pressure alone is not enough. Plus any vacuum leaks on the hose, or indeed any other vacuum leaks on the manifold, will affect this sensor's signal.

After locating the MAP sensor, disconnect its wiring harness.

To test the MAP sensor, run jumper wires between its terminals and wiring harness per the service manual's instructions. Turn the ignition to the ON position and take a voltage reading. Spec for this MAP is about 4.5-5.0 volts.

With the engine running and warmed up, take another voltage reading. It should differ from the non-running number and fluctuate when the engine is revved. If not, verify that the vacuum line isn't damaged or blocked.

If the vacuum line checks out, the sensor is likely faulty. Replace the bad MAP with a new one by connecting the vacuum hose and wiring harness, then securing the sensor to its factory location.

I would check for vacuum leaks and check the sensor good.

Let me know how are you doing!

Hello Kevin!
How are you been?
Well lets continue, i think that its working good when cold because of the cold start valve (extra fuel when cold)
here a picture of the MAP sensor:

the complete picture:

I`ll be back with the spec.

Hey Kevin..
You should run "jump" wires to the MAP sensor to be abble to get readings here is the spec:

here is the connector:

The eggy smell indicates a possible fault with the catalytic converter.

As to the misfiring, have you checked the spark plugs and related components, fuel pressure etc?

Sounds like the timing is off. Possible problems: Distributor is off, wires are on wrong, or timing belt jumped some teeth.
Check to see if timing is OK or not. Also check for a plugged or restricted catalytic converter (exhaust).

Hey Kevin!

Thank you for choose 2Carpros.

It was a pleasure working for you.

We wish you the best!

Hello Kevin!

Yes. Could be the case. Remove the timing belt cover (the top cover) without remove something else and check the marks on the crankshaft and camshaft sprocket.

Let us know and good Luck!

I would say that the fuel delivery system is doing its job, but the spark or electrical side is not performing efficiently. I would check the EGR valve and PCV. Then I would look at the plugs. I know you replaced them recently but I suspect they may be fowling. I mention this because the plugs may point to a specific cylinder that is having problems, a bad plug or wire, bad injector, etc.
