Start off it's a 90 240 ka24e five speed I got the car ran great then put new cap plugs wires and a button on it ran even better then got in it the next morning and had to give gas to even get to crank and would not even idle and had no power so I checked the ecu threw three code for air temp sensors replaced that and then it threw code for Engine temp sensot replaced that then it threw code for the mass airflow sensor which was built in with the air temp sensor and it still throwing code for the mass so I checked the fuel filter had rust in tank really bad almost like sand in bottom so I bought a new gas tank fuel pump sock blew the fuel lines out now Idle but still has no power and cuts out when I get up to about four grand in every gear I don't know what else to do and my daily advice would be much appreciated

Intake Air temp sensor (IAT) and Mass air flow (MAF) sensor are different.
Air filter could be dirty and MAF could be dirty or faulty.

We'll it's new maf and iat sensor is built in wit the maf on single cam cuz I tried ordering the iat they told me didn't show up I may be wrong but it's running better the cat was stopped up but still cuts out at 4 grand and then starts back up around 3 just replaced clutch fly wheel pressure plate and throw out bearing and put short throw shifter on it just don't have the power it should et me know what you think

Correction meant to put AIT sensor
