So I've been trying to solve my cars misfiring and bogging under load problem for the past few days. Like I said in an earlier post it ran fine the last time I drove it,but after sitting for a few days it started acting up with its current problems. I thought i pretty much had it traced to bad gas. It has been raining alot lately and it just came to my attention that the station I frequently use has tank problems, that and the fact it has happened before (last time I wasn't sure which gas station). This is what I have done so far.

1. Put a bottle of heet into tank and ran it for a bit.
2. Drained gas tank and put in 5 gallons from another gas station.
3. Added another 1/2 bottle of heet.
4. Changed fuel filter and spark plugs.

It terms of fixing the bad gas problem I would think I would have pretty much covered everything. I ran it for a bit afterwards even though the problem persisted to get any of the untreated fuel stuck in the lines out. I have also unhooked my intake and exhaust from the header to make sure nothing was clogging my air flow. Under load it feels exaclty like someone has jammed my exhaust or intake up. However, even if my exhaust system was partially clogged I wouldn't think it would create misfiring.

I have also checked my cam gears. Nothing has changed. VAFC settings are good. Spark plugs were very fouled out from running VERY rich. They were soaked VERY black. I find this odd considering I have changed nothing and at my last plug change they were a nice golden brown color.

Is it possible one of my injectors could be bad? I'm also wondering if its possible that my timing belt has slipped and caused me to be extremely retarded. However this is not likely because I sure as heck think it would be alot worse if my car jumped a whole tooth on the timing belt. Any ideas on how a good running car can go bad from just sitting still for two days? Mileage currently at around 74,000mi. Thanks in advance.

 

.....did you check your entire ignition system?

any cel's?

Just replaced plug wires, distributor cap, and rotor button. It is throwing a misfire code on cylinder 1 and 3 but nothing else.

 

I WOULD CHECK IGNITION SYS. TOO....

 

VAFC connections all soldered or crimped? I've heard of bad connections causing major headaches.

 

switch injectors around clear ECM check for codes again if its same look elsewhere
could be on your ignition system mechanical or sensor problem fault (02 etc.)
may need to be traced by qualified tech some problems are not easily figured out.
goodluck.

 

The ICM in your distributor may be crapped out. It's not hard to pull the distributor & test the unit with a multimeter.

 

Hook up a spark plug wire tester and see if you're getting spark to all cylinders. My ignition coil crapped out recently.

 

A couple months back, my #4 injector stuck open on my B16A. The car poured whitish-blue smoke, stunk like gas sooooo bad, and had gas puddles coming out of the tail pipe. The car bogged so bad, and had barely any power what so ever. I got about 10-15miles on a half tank of gas.

I got another injector, swapped'em, and the problem was solved.

EDIT: My #4 spark plug was DRENCHED in gasoline and was obviously beyond fouled, lol.

 

Maybe its the distributor. Happened to me in my old car, and started running on 2 cylinders.

Sounds like my problem maybe just not as extreme. The plugs were all definitely fouled out from whats seems to be running VERY rich.

VAFC connections are all soldered. I've had my distributor go out once and it wasn't like this, but I'll check.

Looks like I might have to let the dealer/warranty take care of this one.

Also could bad gas cause this or would it be from something else?

 

I had injectors go out on me on a 92 civic ex a few years back and I thought it threw a code when they go bad? no?

 

When my injector stuck open I got no codes. So I'm not real sure if it should throw a code.

Yes it would seem that the car should throw a code 17, but it isn't or wasn't yesterday when I checked.
