You checked the spray pattern on the injectors? You checked to make sure they're firing off correctly?

It honestly sounds like your secondaries are clogged. Pull the rail and injectors, use mechanics wire and read the fsm on how to test the spray pattern on the secondaries.

how did you clean them? It requires special tools.

My thoughts exactly.

Usually, and I mean usually; cleaning injectors require ultra sonic bathing, back flowing, and taking measurements throughout the process to ensure that they are flowing properly.

Flow benching the injectors to +/- some percentage and cleaning them until they reach that percentage. You can not just pour in some injector "cleaner" as that only is alcohol, and doesn't really do much of anything... if at all.

You can get injectors semi-cleaned, but that's mostly just fuel system upkeep where they pour in different cleansers through the system. This is not an injector cleaning!

Injectors are sealed units and as such can only be cleaned certain ways as already mentioned.

Dipping them does nothing but remove deposits from the outside of the injectors (and even then it's poor at that). Check the flow and get back to us.
There's no sense in moving forward to another cause until you know that the most likely cause is not it.

sorrie i havent been on for the longest time but my car starts and runs good now just gotta clean the injectors still yet though cause i can feel it pulling back a little at full throttle but other than that all i did was change the TPS with another cars one and it ran fine after that so im guessing it was a bad TPS
