Bad idle, hesitation on acceleration, DEcreased performance and gas mileage.
if you take the car to autozone, they should be able to check it for you with a scanner. if not, then you should take it to a Pontiac or any GM dealership. i had the codes checked in my 97 grand am gt 2.4 and they told me it was one or all of the following. 1. oxygen sensor (o2) defective a. poor connection @ the o2 sensor b. check circuit-fuse 2. knock sensor a. defective b. check connector and wiring sensor c. engine mechanical condition- knock or rattle in engine d. low fuel- pressure 3. coolant temp always low a. check coolant level b. thermostat defective c. ect (engine coolant temprature) sensor defective 4. evap (evaporation emission system) small leak no/ flow condition a. defective or loose fuel cap b. evap canister or hose cracked-not connected c. purge or vent solenoid defective d. vacuum leak at engine hope this helps you out
the lights flash in sequence to show dtc's (diagnostic trouble codes)count the #of flashes and that is the # of the codefor example if u r having a problem w/fuel inj. or main relayu should get 16 flashes then about a 3 sec pause then the code willrepeat unless there is more than one code so watch closelyevery 3 sec pause indicates the start of next codeTo find out what each code means, check this table:1) Primary oxygen sensor- Defective circuit or unplugged/ Defective sensor2) Oxygen sensor "B" - Defective circiut or unplugged/ Defective sensor3) MAP (Manifold Absolute Pressure) Sensor - Defective circuit or unplugged/ Sensor4) CKP (Crankshaft Position Sensor) - Defective circuit or unplugged/ Defective sensor5) MAP (Manifold Absolute Pressure) sensor -Mechanical problem/ Disconnected piping6) ECT ( Engine Coolant Temperature) Sensor- Defective circuit or unplugged/ Sensor7) TP (Throttle Position) Sensor -Defective circuit or unplugged/ Defective sensor8) TDC (Top Dead Centre) Sensor -Defective circuit or unplugged/ Defective sensor9) CYP (Cylinder) - Defective circuit or unplugged/ Defective sensor10) IAT (Intake Air Temperature)sensor- Defective circuit or unplugged/Defective sensor12) EGR (Exhaust Gas Recirculation) -Defective circuit or unplugged/ Defective sensor13) Atmospheric Pressure Sensor - Defective circuit or unplugged/ Defective sensor14) IAC (Intake Air Control) Valve- Defective circuit or unplugged / Defective sensor15) Ignition Output Signal - Missing or defective ignition output signal16) Fuel Injector System - Defective circuit or unplugged/ Defective fuel injector17) VSS (Vehicle Speed Sensor) - Defective circuit or unplugged/ Defective sensor19) Automatic transmission lockup control Solenoid Valve- Defective circuit or unplugged/ Defective solenoid.

It does not have a mass air flow sensor.
Bad gas, water in fuel, Low fuel pump pressure, dirty air flow sensor screen, one or more engine sensors defective and/or out of normal reporting ranges, engine control computer defective. Low battery and alternator output. The "check engine light"should have come on to give you a hint.

That is a NO NO. You should never clean the mass air flow sensor it will mess it up.
It does not have a mass airflow sensor.
On a 2002 Ford Ranger : The Mass Air Flow Sensor is between the engine air filter and the engine air intake tube
the symptons include very poor acceleration, poor engine performance, and also the engine coil packs tend to blow up quite often and the oxygen sensor will need replacing.
It doesn't have a mass air flow sensor.
There is not a mass air flow sensor on a 1997 Dodge Dakota.
