0bd2 gsr
problem Lags or skips at 3k-3.5k ish gains power when floor boarded
all cylinders are getting fire
New Distributor,spark plug wires, spark plugs, and head gasket
check engine light by autozone only says misfire cylinders 1,2,3,4

I'm thinking map sensor

Hm, cylinder misfire in Cylinders 1,2,3,4. you think its MAP sensor. Hm...... Eh..



Is your firing order right?

flatside up it should be

3 4
1 2

cylinder nearest crank pulley being 1

I mean I havent touched my motor(besides to check oil level) since about 4k miles ago when I replaced Distributor,spark plug wires, spark plugs, and head gasket so i don't think so but ill double check. theres two sensors attached to the throttle body think its the one faceing toward the firewall

Check timing with timing light, is idle ok

If it has a miss fire on all 4cyl I would check the crank sensor and wireing its very common when people do timing belt jobs on these they dont tuck the wires back where they should be and the wires rub the alternator belt anf will throw a code for a miss fire on all 4 cyls

Check your fuel pressure.

Learn something everyday:yes:

since my car has the service port i didnt know it had the handy black and brown wires for you to jump together so im sad to say i just found several codes
6- Coolant temperature sensor or circuit
23- knock sensor
41- Oxygen sensor heater ( Integra), front oxygen sensor heater
47- Fuel pump
73- Misfire, cylinder no. 3

Honestly where should i start... money is a problem right now and its a obd2 acura at that

check connections to coolant sensor (below distributor, single 1 wire plug), ignore knock.. it wont kill you, change o2, change fuel pump & fuel filter, and open dizzy and check/clean internals.
