My son has an 89 Olds Delta 88 3.8L V6 with 110K miles. It slowly (over
months?) began getting hard to start. Hot or cold engine or weather.
Can only start it now with a squirt of starting fluid in the air filter.
The MAF sensor has to be UNPLUGBED to start at all.
When it does start it idles OK but lacks power at low and high speeds and
wants to "pull back" or stutter?
There are no error codes from the slef-diagnostic lights.
Have replaced the O2 sensor, MAF sensor, fuel filter, air filter, plugs, and
Have checked the vacuum, fuel pump pressure, and throttle positioning
I've heard of a crank sensor but can't seem to locate it if it has one.
The throttle body was carboned up, cleaning it did nothing.
Am at a loss on this one. Any help????
