I have a 1995 honda civic 1.6L vtec. Ok so I recently rebult the engine and head and its been running fine but I noticed that there was a leak from the distributor. I didnt put tighten the bolts all the way or something so I took off the rocker arm assembly so it could go back in. Put it all back together. And it starts right up. Oh during this time I also fixed a vacuum leak I forgot to use some gasket maker when installing the throttle body spacer. When I start it it runs fine and as soon as I start it I can rev it up as far as I want but after about 20 seconds of it being on it wants to die if I press the accelerator. The car has been down for a few weeks and ive tried alot of stuff. Replaced pcv valve rotor button. Cap seems to be fine. I fiddled with the ignition timing and valve timing changing both as much as the adjustments would allow. And no change. The exhaust smells like fuel. Ive recently replaced the fuel pump and fuel filter. It doesnt make sense that the fuel pressure regulator would just go out. So ive been thinking that it was the ignition and not fuel delivery or air. I checked resistance on the coil and its good. Oh heres something wierd. So after it warms up I can press the accelerator to get it up to about 1.5 to 2k rpms and I can keep it there. But it sounds like its misfiring when I do that.
I have checked the TPS, IAT, and MAP sensors all are good. One more thing when taking off the head you have to remove the coolant temperature sensor. But to do this you have to twist the wire as you back it out, theres no way to disconnect it from the harness from what ive seen. I didnt think it was the coolant temperature sensor because the display has a temp gauge and it comes up to operating temp. It takes a little while since I dont have the thermostat in but it does.
please help me. I dont know anyone who has messed around with cars that much and im kinda a poor college student or I would have taken it to a mechanic.
have the same problem?
