1st problem : At sometimes my car has no throttle response..TPS sensor??what should i do?

2nd problem : Car does not always have v-tec...Pressure Switch??what should i do?

The car throws 3 codes..1, 7, ans 22

1 = o2 sen

7 = TPS sen

22 = V-tec Pressure sen

You need to trouble shoot the codes to eliminate and find what is causing th codes. A Honda/Acura service manual will have all the steps to do the trouble shooting.
 
You said VTEC does not always work, so when does it?

As for the o2 sensor, is it an OEM sensor?

The TPS has got to be some sort of a wiring mixup because you are running an OBD2 head with an OBD1 ECU, I'll do some research and see what I can find.
 
every sensor has a test procedure, you say you have have a chipped P28, have you thought about getting it tuned properly?
