Pat, with his Broken Sunbird again.
Tuesday, January 29, 2013 8:45 PM
So,

While the site was down my car decided to be a jerk. I replace the plugs and wires on my car, 3(plugs) of which were fouled. Now, its taking a charge. . . But decided to pic up a terrific new trait. When the engine gets warm, the oil pressure and the RPM's drop down and it will stall if I don't keep it up at 800rpms or so. . . So, is it the mass air flow sensor? Fuel filter? dirty Injectors? All of the above?

I got a Haynes Manual and it offers some vague answers in the troubleshooting section. What I want is to hear from you guys and see if one or more of you have had this same issue and any advice you can provide would be greatly appreciated

Thanks,



Pat, the broke single Dad with a 91 Sunbird.

I am def tired.But a quick idea it could be your map sensor or your tps or the iac valce (idle air control) or even some of the 2nd gen guys said a cracked vacumm line on the cruise box will cause irratic idle and or choke or die.I will shed some more light on this wed and share a link I used to learn how to check all those pesky engine sensors.You will need a multimeter to do this check on those sensors too.Unless something like your EGR valve is so gummed up from carbon it will make it idle crappy,not run once warm(especially this) and can be removed and cleaned and or remove the vacumm line going to it and see IF it clears up the idle issue.Try the egr 1st and laying odds on any of the items I listed as being possible.
