Default What can i do now???

Why does engine light still come on? when engine light is on-truck runs great, lots of power and when it is off truck has no power doesnt drive good. I just changed the
mass air flow unit
Plugs and wires
Gas
Batt

What can i do now? Counting codes with lights and waiting 4 sec between numbers is not going to work for me? Buy a Throttle position sensor? We had to adjust the throttle cabe today to make the rpms from being to high, I changed the iac unit but the new makes It worse, so I put the old one back on,

Knowing the code or codes will help find the problem otherwise we're guesing.

Is it misfiring,looping idle,stalling,or something else.

Check all the electrical connections and vaccum lines.

it sounds one of your sensors is bad which one i couldn't tell you

when the light is on the computer is running a set mixture when it isn't it is adjusting the mixture according to the data available by the sensors

Well it's finely fixed, after a month or two and lots of parts i didn't need but I guess it will help in the long run. Anyways it ended up being a wire (throttle sensor cable) got caught between two parts last time it was worked on, and was not grounded. Needs a new starter then we are good to go! Old owner put a used starter in it and it has a dead spot! Still happy about getting my truck running tho
