i have a 89 2.8 i did a tune up wires, plugs, cap, rotors, ecu. to try and fix it. it idles at 7-800 but dips to 300. sometimes it stalls the car. if in park it does not stall, but if i put it in drive or reverse it sometimes will stall. I was thinkng injectors? I took it to a dealer to get the wirring from the fuse box to the injectors replaced because they were shorting out and turnning off the passenger sind bank of injectors. so i think that may have craped out the injectors. i havent change them in 190,000 miles. i do have an exhaust leak but thats been there for a while. any help is greatly appreciated. my other car is also starting to crap out so i need to try and get this going. thanks.

 

Are you getting any codes? This could be a few sensors.
