When i accellerate anything past 40% throttole or so the engine vibrates quite a bit, otherwise it appears to be fine. Also, it appears to get worse as the RPMs raise. I fouled out 2 sets of spark plugs already, 1 set of iridiums, 1 set of the cheap NGK's, and the cheap ones lasted longer. Basically when i pop in new plugs everything seems great for a little while, then the side effects above happen. I get carbon deposits on my plugs, and in first after the plugs have been in for a few miles i have to rev it to about 2k to release the clutch, otherwise it will stall on a slow take-off. I checked my fuel pressure and im getting 43-44ish psi at idle, which is within stock. Im using a walbro 255 fuel pump, stock injectors (sent them out to be cleaned & tested a while back) and the rest of my GSR is all stock. I'm thinking maybe my injectors aren't holding the fuel, and some is sucking out with vacuum or something similar... at first i was concerned it may be due to too much fuel pressure with the high rated pump, but the pressure seams fine.


On a related note...car died on an onramp to the highway, sheriff came up behind me after about 10 minutes of fiddling with the plug wires and such in the engine bay. Come to find i have a warrant out for my arrest due to a letter sent to me with a court date which i never got due to my dad being in the hospital for many months... and this was all on the way to work. The phone card they gave me (to make your calls while in jail) didnt work, and they refused to give me a new one. They take your money when you get in, then mail you the check after, so upon leaving i had no money. The officer took my phone out of my pocket on pat down, and threw it in my car, so here i am out of jail 8 hours later, with no money, no way of calling anyone. After complaining for 45 minutes to the attendant in the main office that cell phones and the only land-line that i needed to contact were not accepting collect calls, she finally gave me a bus token... Then i had to complain for another 15 minutes to beat into her head that the nearest bus stop to my house was about 5 miles. FINALLY after spending my whole day, unable to call into work, or call anyone, at 5PM i was given 50 cents after speaking with 4 different officers about the completely ridiculous circumstances in order to make a call.

Moral of the story....fouled out plugs put me in jail.

up..

 

up...checked the o2 sensor wiring and everything looks right. There are 2 wires that are the same color, tried swapping them with no change....cmon someone.

 

check engine light on? hows the valve adjustment? miles and how are the wires, dist cap and rotor////

 

no light, just got the head back from being rebuilt, assembled, and attached to my block. Brand new dist, new MSD wires


the motor idles great, very quiet.... when i first take it out i can maybe get 1 good pull, but after that it starts to get the weird hesitation after about 3k,then it starts to require about 1200RPM's before i can back off the clutch, etc.

u need to check your valve adjustment, i just had a teg in a couple weeks ago fresh ls/vtec build, the guy just had everything done and the car would idle fine but if u went past 3000rpms the car would bog, his head was just redone ie valves, springs, cams, and i had to adjust his valves and that fixed everything. im not saying its the valve adj--but its a good start and its easy. another thing are u running a stock ecm.....

 

im running a p28, same thing as stock except it doesnt have a knock sensor.

 

I would check my inj pulse, o2 sensor, and ignition system.

what u really want check at first is fuel trim both long term and short term but do you have a scan tool with that capability available.

 

i think im going to chip it with hondata, i was told a p28 wont p ick up secondaries. Apparently i was instructed to get this for use with my supercharger, not n/a. So im going to chip it and basemap GSR it i think. I cant scantool because im obd1 with an obd0 interface connector, which i cant find anyway...i think the guy that owned it before me hacked it off.

 

looking for an obd1 p72 now.. uppp

 

just got a p72 plugged in...no change, someone help me out! been in this non-running state for about 3 months now, bleh.

 

anyone have an idea? I also noticed about a week ago when i was driving it on the daily it wasnt doing this so often; i had actually driven it on the highway about 10 miles. Now i wasnt reving it up as high, but i was still running about 2500-3000rpms and youd think i would have fouled plugs then. It's almost like whatever is causing it, is slowly wearing or getting worse.

 

maaan wish i could help you out.....BUT I CANT!

 

I appreciate your desire.
