Recently i've been using 93 grade of gass and it helps to get pass that ****** 3800rpm.. i'm still working on getting pass it by just mashing the peddle and let the engine do the work.. i'm replacing the spark plugs and see if that would help... this is what i'm doing before i start doing any work to the engine.. and can anyone show me a pic of where my 5th and 6th ports are? and where my fuel injecters are at.. cuz thats what i was told to do to pass 3800rpm.. some say its the ecu.. i dont know.. can someone let me know what's needed to be done..thanx..

 

I have an 88 Convertible with 57000 miles. I was getting crap for gas mileage and I swapped to premium and was shocked at the difference.

 

Replace your O2 sensor

And coke, How is the ground on the rear rotor housing doing? 5th and 6th ports are right above the exhaust header. They look like little pots with rods coming out of them. Also, get a factory service manual, or a haynes manual (I reccomend both). Also, whats the story on your car. Howd you get it, and what was it doing before you got it?

 

well the thing is that im not to familiar with the engine just yet.. i just got it like a month and some change ago.. i have a manual... i'll take a look at it in the morning.. Well i got the car from a used car dealer.. it only had 8500 miles on it.. and got it for 2500 bucks.. (i was in desperate need of some wheels).. the brakes were bad and body was dirty and interior was dusty... i took it home and did a detail cleaning.. but the brakes were still a lil noisey.. (they still are but much quieter now, need to get new rotors and capilers).. i tinted the windows changed the air filter sparkplugs, exhaust.. working on getting new spark plug wires and emblem by nxt week... then paint job and air intake, also 17" rims.. that's basically it about the car...
