Hi..

i have a Civic 95 EX Coupe, D15b vtec Swapped, P08 ECU, A/T.. my problem is

when i release the gas the rpm drop down below 1,000 fast, when the car do that running it feel like the car is breaking, in idle do something similar if u rev up the car when release the gas the rpm drops down very fast and it have a little smoke smell.

changed EACv, TPS, ECT, FITV, Oxigen sensor is new..

Any suggestion?

 

vacuum leak?

 

Any mods to the car?? How about the distributor/spark plugs? When was the last time SP were changed? When was the last time dizzy was serviced?

Also how does it drive? Bogging? Loss of power??

 

spark plug are new, wires too, i dont hav changed the distributor jet, my car does not have any mod, exept the engine swap. it hav very loss of power when release the gas..

i dont know if it can be fuel inyectors or fuel pump, because in the morning at cold start, the engine start great except when i press the gas and the car get missfire

any idea???

 

Any CEL codes?

Replace the cap and rotor and adjust the ignition timing to spec and then go from there.

 

cap and rotor replaced, symptoms still :\, no CEL Code and mi timing is in good shape

 

I read that the map sensor can cause something similar, is that true?

 

What do you mean "timing is in good shape"? Is it in time or not. Did you actually check it?

 

My mechanic says, that the time is good

 

all these symptoms are more notable after the engine get warm to operating temperature

 

any body??

 

get a heavier flywheel, do you have a lightened flywheel?

 

noo, my engine is stock

 

Problem Solved.. was the TPS plug, one of the wires(ground) was semi broken in the base of the plug, replace the plug an solved

thx
