1st thing to do is test the system for codes, the problem is most likely a failed or stuck shift solenoid indside the trans, have you ever serviced the trans, sometimes a fluid and filter cahnge will cure these kinds of issues.

Still need the codes.
Injectors can go "bad" in a couple of different ways; all they are is an electromagneticaly controlled nozzle. When the ECU "fires" the injector, it pulses a ground circuit for 4-8 milliseconds, the electromagnet powers up, the valve at the bottom of the injector opens, and the fuel shoots out, under pressure. The wire can be bad/chafed/corodded/ The electromagnet may be weak. The nozzle may be stuck. Lots of things. But, to put in an injector for a number 4 cylinder misfire (p-0304 code) would be one of the last things that I would do.

What you need to do is check you fuel pressure. Go to a local auto parts store and buy a fuel injection pressure tester. The pressure fitting is on the top of the motor its a 3/8 ish sized metal line and has a screw on fitting like a tire valve does. This line comes up from the back of the motor to the right of the distributor and goes down into the intake. Make sure to have a rag handy to catch the fuel seepage. After you connect the pressure tester turn the key on and off three times and read the gage you should have atleast 58 pounds of pressure. If you have 56 pounds it won't run because the fuel injectors are a poppit valve style and need atleast 58 pounds of pressure to operate.

SOURCE: surging power lose

a maf sensor will cause this also,you can go to any auto parts store and buy the maf sensor spray. follow directions on can. make sure air filter is clean also. my car did the same thing and after I cleaned the maf sensor it has been fine. 3.1 engine, to check sensor, just unplug it and try it on hills or highway. the car will not run very good and may stall out, but if the car does not surge, the maf is the problem.

check your air intake control switch: it is on the manifold and, is attached to a flap inside the intake; this switch's flap should be easily moved by the air from the aircleaner and, tells the engine computer that you have the right amount of air coming into the engine for fast acceleration if it fails the engine computer will not know the amount of air available to sustain rapid spark speed lastly check the installation of your air filter I have seen very dirty ones and, some inserted upsidedown there is an arrow that should point to the engine

ENGINE LACKS POWER (4AGE) 1600 CC, 4 CYL, TWIN CAM


I had the fuel pump recently replaced i just assumed the fuel filter was replaced also cause my fuel pump is in the gas tank. My air filter is clean and I have 4 fuel injectors, no carburetor. A friend of mine who has looked at my car for me says it sounds like there is some kind of air leak but can't figure out where it is coming from?
