I got a 88 isuzu impulse a month ago.At first it was nice and got "some power". But aftyer my brother floored the pedal shifting at 5-6000 rpm, it just kind of pull back. 1st gear goes up to 3-4000 rpm only doing like 5 mph. I checked the air filter and it is very brittle and crispy. I am having a hard time looking for parts so i can't replace the air filter yet. by the way i think the car also had been sitting for a while. I just change my oil and when i checked it was black already. help please!!!

You might want to clean out that turbo with some carb cleaner. You probably have some real nasty exhaust build up in there. Replace the air filter, and clean out the throttle body with some carb cleaner as well. You probably have a real dirty intake system which is restricting the air going into the engine. If this doesn't fix your problem, check for air leaks along the intercooler. This can really rob you of power.

You need to install a boost guage and check to see if the turbo is working. You will need to find out what the factory spec on the boost is, and see if it's close to where it should be. If not, the turbo may be shot and need replaced.
