Is it possible its the IAC that needs replacing? Have a check engine light but havent ran a diagnostic on it because I know it will throw out sum code that dont make sense. What you guys think needs replacing cuz I have new 42lb injectors a fuel filter with less than 3000 miles on it. Just replaced the TPS not that. and have a new cam shaft sensor on it. My thinking fuel pump going out, maf going out, catylitic going out, bad o2 sensor, what do you all suggest first or should I get a diagnostic but im sure it b a bull code?

maybe this will help. when I give the car gas it stumbles then its okay for a second then when I shift into 3rd gear and give it gas it stumbles again and so on into 4th and 5th gear. But like I said it does idle roughly in the garage, while its parked with the emergency brake applied. Could it be the IAC? I do have a check engine light that I can get diagnose at autozone, but like I said it will b a code that dont pinpoint the problem, it will be a code that will be pretty vague.

Now that i have read alot on this forum about rough idling no one has mention bad catalytic convertors. Is that a possibility on my idling problem and acceleration problem of being herky jerky then its okay alittle bit whiled almost floored. I still feel like it wants to crap out after it gets past 4600 rpms but feels better at those rpms through all the gears than below it but still feels ****ty like Im losing horsepower.
