I have a 94 honda del sol si, I had a few problems with the engine, first it started with the honda idle and it got progressively worse. Then i would put it into gear and it would die when i would give it gas and let the clutch out. After a while of looking for problems like vacuum leaks or other problems it finally through a code, that then lead to me replacing the throttle body since a stock one is expensive. I put in a new blox biliot throttle body with a new tps sensor. The problem go alot better but i am still have troubles, like the car running like crap when cold. And after it gets warmed up gets the honda idle, and sometimes will still bog down, just like with the stock Throttle body with the bad tps sensor. I could not find any vacuum leaks with my new setup and am stumped on what to do. Has anyone else had these problems? I have heard about cleaning the IAC and the FITV sensor is there a guide that will show how to properly do it? Thanks for the help.
