my car is throwing 5 codes.
3(manifold absoute pressure)
7(tps)
10(intake air temp.)
14(idle air control valve)
21(vtec solenoid)
i have a obd1 gsr in a 1996 civic hatch. it ran perfect before but then i had a shop put in new vavles and now it doesnt run right. anyone know what could be wrong.

 

Check to make sure the correct plugs are going to the correct sensors.

 

yes i did that used a haynes manual for reference

 

take it back to the shop and make them fix it. I assume you told them the engine was not stock, and to get parts for a GSR.

 

That's what I would do.

 

it's posible that intake temp sensor connector n idle r swap n check tps n map too.

 

yea i tried switching them still throwing the same codes

 

check all fuses and ecu connection. does engine idle. what do u mean it doesn't run right.
