your car will not run well like it is choking and the eng. light will be on the best thing to do is get your hands on a hand held diagnosis computer (most any auto part store will do it for free thats how they sell product) the diagnosis tool will kick out codes that you or they can look up and will tell you what is wrong. the auto part store can print out a tool list,some specs,and location-how to fix it also. find a parts store you trust they can help more then you know
I would suspect the map sensor is bad.
Timing, a bad plug (s), bad plug wires, bad maf sensor, bad map sensor, bad o-2 sensor, bad ign. Module
MAP sensor going bad will cause that exact symptom, try unplugging the MAP sensor, if the vehicle will run with it unplugged then you know the MAP sensor is bad. My 88 Dodge Aries did the exact same thing.
The TPS is not happy with the readings from the map sensor. More than Likely you have a bad sensor.
You can not prevent a sensor from failing.
Yes....the MAP sensor tells the computer the amount of pressure or vacuum in the engine. This changes with throttle opening....etc. If the sensor is bad the settings will be bad. The MAP sensor can be tested for free at AutoZone.....and you can just take it in. They don't need it on the car.
how do you k now the cam sensor is bad
bad oxygen sensor bad map sensor
yes
engine will stall out and run very bad.
you prob. have a bad map sensor. to test map sensor, put the + lead from a dc meter on the center wire that hooks up to the map sensor and the - lead to ground, you should get a reading between .5-4.5 volts any thing below or over map sensor is bad
Sounds like you might have a bad map sensor, i don't know if a 1990 would have a MAF sensor or a MAP sensor I would assume MAP.
