TRYLSTEG808

i have a 99 Acura Integra LS (stock) I was cleaning my throttle body and after i put it back my CEL went on.

I had a friend ran a diagnostic on my car and the OBD scan reader showed " MAP HIGHER THAN EXPECTED CODE: P1129" My friend is not that much educated about Hondas neither do I.

Need to know what this code mean and what repair is needed. I dont want to go see a mechanic at first and give me nonesense repairs just to make money off my ***. I already had been through a bad experience with mechanics.

HELP ME OUT PLEASE

delete the code and wait and see if it comes back, but as far as fixing the problem maybe a new map sensor but clear it first and see if it comes back.

I have a 1998 Honda Accord with a 2.3 . Just R&R'd the motor . Never had codes on old engine before timing belt went. New engine has DTC p1129 MAP pressure too high. R&R'd MAP . Still surges . I would like some help with this as it's becoming a pain and the obvious answers arent working.
