So if you were getting terrible gas mileage like I was . Be sure to check the following
- Fuel pressure regulator an fuel filter
- Spark Plugs an Gap, should be .44 I believe
- 02 sensor, they do go bad their 30+ year old cars haha
- If your car is Automatic check egr passages.
- My Case a clogged catalytic converter , take it off super easy an hold it to the sky an try to look through it. If you can see through it just fine no problem if you can’t I just hollowed mine out
.
- Tire pressure
- PCV
- Clogged return line
- Air filter or on stock da intake tubes they have a secondary filter on top 4, 8mm bolts I believe. Found that mine was absolutely terrible.
- Distributor Cap an rotor.
Basic maintenance stuff makes these cars run forever , an over 30 years you have to expect something small to happen.
