Hi there, I have a 98 GSR. I took the motor out and replace it with an LS. I drove it for a few months and it starts bogging on me. When I start it up and the motor is cool it won't bog.But when the temperature get to normal temp then the car start to bogs,even when you drive it.If I push the gas full throttle then it'll bog on every gear and I'll have a slow acceleration on the hwy.Any help please...

So far I have replace these parts...
-Fuel filter
-Spark plugs

 

i hade the same problem thought it was spark plug wire spark plug and distubrator i change all that out and it work for like a lil ,because i hade check engine light on , it said miss fire ..... so i took it too my freinds and he look at it all over and it was bad FUEL INGECTORS .... try that or your wire is messed up or un plug

 

are u running the ls ecu??? does ur car idle properly around plus or minus 750 rpm.Check ur timming on ur cams, it could be off.It makes a huge difference in power.When i first got my car mine was off slightly and i lost to an ex civic.after i fixed it i burned him about 3+ cars lol.

 

hmm...It will bogs all the way if I push the gas hard. But if I leave it on neutral it sounds fine. And yes I'm using the p75 ECU. I replaced the injectors but is still the same...Any help???
