after driving my car for about 10 or 15 min, it has a dead spot around 2k rpms. i did a small tune job - plugs, wires, cap and rotor button but the problem is still there. i have a 93 eg hatch with the d15b7 in it. any ideas??? is it maybe the coil? also, when this problem begain my gas milage really bit the dust. plus no power. if i could just get some ideas of where to start next that would be great. thanks for the help.

 

What the hell is a "dead spot"?

 

What is a dead spot?
You mean like the cars rpms stuck at 2k and can not pass it? How does it sound? Does it bog, sputters, lack of power?

sounds normal, bogs bad, lack of power is just on bottom end of gear. sputters somewhat. hard to explain. lol. what would you say it is?

 

Umm its been a few years back when i had that problem
First thing i would do is check the dizzy, it might be the coil also.
Check the o2 sensor it might be bad, since o2 tells the ecu how much fuel to feed.
Also check the map sensor or tps.
I dont know if these things i mention might help or not. Some one here should know the problem.

 

thanks ill check it when i get off work and post up what happens tomarrow.

 

its the weirdest thing. i replaced the fuel filter and did a clutch master cylinder yesterday and my problem is gone.

 

Good to hear you fix the problem. I think the fuel filter probley clogged up or something.
How many miles was on it?

 

Because i had another problem, the rpm was cutting out at 7,000. Couldnt find the problem until i sold the motor. New motor when back in an had the same problem. Stupid me forgot to put a crush washer on the bango on the AEM fuel rail.

its right at 120k miles. fuel gauge doesnt work so ive been running it out of gas alot. i probly picked up lots of crap out of the tank and got it stuck in the fuel filter. its just weird that it would only do it at low rpms.
