This is most likely a failure in your antitheft system shutting down the fuel injectors.

bulb is loose or going bad. pull cluster and it comes out the back.

Sensor 2 should be in or immediately after the catalytic converter for bank 1, assuming that its true dual exhaust and dual cat.

dont think they have vacuim lines most 90 model &up run eletronic sensors but iam not 2 sure

It all depends on the outside (ambient) air temperature. Your A/C low pressure switch is designed to turn the compressor off at 24 Psi. and turn it back on at 45 Psi. Most systems will normally run at between 25 and 40 Psi when the system is running on HIGH blower and "MAX" or "RECIRCULATE". A system that is fully charged may run at 25 Psi when the ambient temperature is 75 Deg. (F) and may run at 40 Psi when the ambient temperature is at 90 Deg. (F). (it can be even higher if ambient temperatures are higher than 90 Degrees.)

To properly diagnose a malfunctioning A/C system, the HIGH side pressure must also be checked. Restrictions in the system can make the low side pressure look normal while the high side pressure is high enough to blow hoses apart. (400+ Psi.)

Look on the underhood sticker. Locate the emissions canister (or charcoal canister). The skinny line coming from it is the vacuum line. Follow it, and it should lead you to the canister purge solenoid.

Hi,

The distributor ignition system supplies two timing inputs to the PCM, a high resolution signal (180 pulses per one crankshaft revolution) and a low resolution signal (4 pulses per one crankshaft revolution). The high resolution and low resolution circuits toggle between 0 and 5 volts as the camshaft turns. The PCM can determine if one of the timing inputs is not being received by comparing the two inputs.
The following malfunctions to the high resolution circuit will cause a DTC P0372 to set:
• An open. • A short to voltage. • A short to ground. • A defective ignition module within the distributor. Conditions for Setting the DTC • The PCM detects low resolution pulses but no high resolution pulses. Action Taken When the DTC Sets • The PCM will illuminate the Malfunction Indicator Lamp (MIL) when the diagnostic runs and fails. • The PCM will record operating conditions at the time the diagnostic fails. This information will be stored in the Freeze Frame and/or Failure Records. • The injector will be disabled for the entire ignition cycle. Conditions for Clearing the MIL/DTC • The PCM will turn the MIL OFF after three consecutive drive trips that the diagnostic runs and does not fail. • A last test failed (Current DTC) will clear when the diagnostic runs and does not fail. • A History DTC will clear after forty consecutive warm-up cycles, if no failures are reported by this or any other emission related diagnostic. • PCM battery voltage is interrupted. • Using a Scan tool. Diagnostic Aids • If DTC P1351 and/or DTC P1361 is also set with a DTC P0372, and no external fault can be found, replace the PCM. If only DTC P0372 is set and the distributor connections are OK, replace the distributor. • If distributor components must be replaced, check distributor vent system operation.
Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

You basically have a engine ignition misfire this can consist of plug wires coil pack and sparkplugs,

Rotate the tensioner pully clockwise using a 13 mm 1/2" socket. (the tensioner pulley is the only one with a hex head bolt). Follow tthe routing guide inside your engine bay and replace the pulley. They can squeak from age even if they don't have any cracks.

Is the security light coming on? The computer chip in the key could be going bad and that will hinder starting. Good luck!

Hi
When I had the problem in mine, it was caused by fluid that hadn't been changed regularly and an extremely clogged filter. All we had done was changed the filter, cleaned the metal fragments off the magnets in the pan, and replaced the fluid with new, and worked. If you have a transmission specialist in your area, most will perform a check it for free.
Hope this gives you an idea on how to solve it.Thanks

If the problem is fixed, it should go out by itself after the driving a couple of hours or so. The car needs driving time to run the test. If it doesn't go out in a couple days, you can take it to autozone or advance to clear the codes. If they come back after being cleared, you still have an issue. OK?

SOUND LIKE STOPPED UP FUEL FILTER OR FUEL PUMP FAILING.
