A little dirty... But the engine was burning pretty good...

What was your milage before the change? Highway? With a 2.84 you should see 30mpg easily

town mileage 14, best ever highway mileage on long trips to florida was 23-24. :(
this is with no WOT, rapid acceleration for me in this car is hitting 3000 rpm! haha

so I have replaced the o2 sensor, on to plugs and wires, I have pulled off the first boot, and I see BOSCH on the old plugs, jeezzz.

looking for improvements in mpg

replacing with ac delco standard plugs and blue napa wires.

The sensor may have been getting a bit lazy... And Bosh plugs and 3800 aren't friends...LOL I get the feeling you have already read about that..

Yes some Good AC Delco Plugs, and wires will help... In the future when you have the time and money I do reccomend a swap to the Delco II ICM and Coils, and then a set of NGK TR55 Plugs... I have done as good as 31 on my 91, and that was with me going over the posted limit on the interstate...

Worst I did was 13mpg in town and 22 on the road with a Bosch O2 sensor... Now the norm is 19-21 in town with the AC On... lol

Gotta have the AC in Florida

I actually had the delco module and coil set from a 1992 98 I think, for a month or so. Then I percieved it'* miss to be getting worse and payed money for new magnavox module and coil, so since those were expensive, I have to stay with them for now.

back outside now.

I can't believe you'll ever see 30 mpg. I never came close to that in my 89 and I'm the original owner.

I have never had a problem pulling 30+ with my 91... and even then i wasn't exactly going slow...

I used to know a service manager that had a 91 SE with the 2.97 gear ratio and he too always pulled better than 30...

On my 95 with the series II I generally do from 29-32 depending on how heavy my right foot gets..

The 3800 C, 3800 L and 3800 K are all SFI engines and should pull some pretty good interstate MPG'*... Unless you have an SSE with the 3.33 gear ratio..Then you might max out at 27-28
