I bought a 1993 Olds 88 in May. Great car but very slow off the line, especially in hot weather. I replaced the cat, bosch plugs, and run mobil 1. Still little has improved. I am new to this forum and glad to see a sight deticated to GM'* big sports sedans. I'd like to find a way to improve my low end torque. Any suggestion would help.

Hey, Welcome aboard fellow Minnesotan.

Try changing your plugs to NGK V-power or AC Delco Platinums.
Do a complete tuneup on your car (i.e. fuel filter, air filter, pcv valve, clean throttle body, etc..)
Also, did you use a Bosch o2 sensor? Our 3800 engines do not like Bosch items.
For more power try a Cold Air Intake (CAI), high flow exhaust system, MSD coil packs, Taylor or MSD plug wires.
Another thing you could try is running 91+ premium unleaded fuel. I know in my 1994 Bonneville SLE (has the same engine as your Olds) if I ran anything less than 91 it lost a lot of power, response and smoothness. Gas mileage was also up 3-4 mpg with premium compared to regular unleaded.
BTW, we have a member here from Lakeville. His name is Jason (user name BonneMeMN) and he drives a purple 1993 Bonneville SLE. WARNING ---- JASON IS A POST-*****.

Opening up the intake and exhaust will do wonders. There'* some on here that are making them. You might PM BonnieMeMN and ask him what'* up. For the exhaust, do a search on here for Magnaflow or Flowmaster. There is a wealth of information of Series I N/A guys that have done this mod. Good luck!...

Not making any right now..... Intake and exhaust are good bets. L27 has one of the lowest torque range of any 3800 though.. :?

I've heard that the series 1 has the best torque, thats why I'm confused. It fells almost like a turbo with serious lag. Its very fast at the high end of the powerband. For those who live in Lakeville probably know about the hill on highway thirty- five heading into Burnsville from the cities. I have to make the tranny kick down in order to maintain speed while climbing. Cruising with the torque clutch engaged makes me lose speed.

You don't have more torque than the Series 2, but you get your torque at a lower RPM. Try cleaning your Throttle Body to increase throttle response. That may be where your 'lag' is coming from.

I know that spot....drive it everyday. I think a lot cars have to shift there, well at least mine does too.

There'* a big hill around here I climb sometimes, a 55mph highway. When my car is on cruise, all it does is apply more boost, with the TCC still engaged and it'* good.

What am I talking about, "big hill"?!!? I'm in Kansas, for God'* sake...

I live in lakeville!!! I'm in mankato during school @ MSU but lets hook up!!

Random thought: Seeing all these MNers on here, I wonder why so many members are up North?
