    ACIS and a vaccumm leak?

    This is probably my last update as I haven't gotten a response in about six days. I cleaned out the ISC. It seems to have helped a little bit. Before the loabing/hunting starts, the car idles a bit higher, but the misfire isn't as pronounced at first. Spraying carb cleaner on the vacuum lines...

    ACIS and a vaccumm leak?

    Cleaned out the ISC yesterday. Guess we'll see what that does. No ideas on what the cause of my problem could be? I'm trying to get a good idea here instead of just trying a relay, pump, switch and injectors at it. Local mechanic said the problem could be valve guides.

    ACIS and a vaccumm leak?

    Another update here. I threw some MSD plug wires on there. It helped a bit, but there's still a lot of missing. Finally convinced my dad to drive it, and this is what he noticed: Under 3200 (or so) rpms, the car misses pretty bad, still kind of a sputter. At the really low rpms (2000 and below)...

    ACIS and a vaccumm leak?

    Every now and then when you crank it, it'll idle very roughly and just keep going lower until it dies. If you try to accelerate it, it'll drive but with a huge miss for about 5 miles and then it'll slowly return to normal. It usually cranks alright, so I really don't see that problem being the...

    ACIS and a vaccumm leak?

    Okay. I'll search for those, thanks. How about the fuel pump or filter? Or the fuel pressure regulator? I've also got a three inch exhaust, custom headers super dragger muffler (From the previous owner, haven't replaced it yet) The throttle is weird, it's I have to floor it to really...

    ACIS and a vaccumm leak?

    Neg on the ISC. What is that? When I adjusted the tps, I hooked up a voltmeter and turned it until it deflected it (analog meter) and then turned it back just a hair. I honestly can't remember if I gapped the lever and the stop screw or not, but I remember someone (Jetjock, I think) saying...

    ACIS and a vaccumm leak?

    Gaps are fine. Plug wires should be as new as the plugs, but I'm not 100 percent sure. That's next on my list, aside from the O2 sensor.

    ACIS and a vaccumm leak?

    We set the timing at 10 Deg. We jumped it too (you put it in diagnostic mode, correct?). Still misfiring under idle and acceleration.

    straight out of a horror movie

    I was wondering if anyone else noticed. They went back to check? Wtf is that? That's the scariest thing about this. Not the actions of one person on the fringes of society, those types of crime date back as far as humans have existed. It's the lack of courage, and the lack of action of 37...

    ACIS and a vaccumm leak?

    Actually no, we haven't checked it with a light yet. Thanks. Btw, I checked all the vacuum lines, they look good to me.

    ACIS and a vaccumm leak?

    I ordered a new AFM and put that on today. The stuttering once it heats up has done away. It's now drivable. But, under acceleration, while the motor revs is still seems like the car is hesitating until it gets above 3000k. And there is a misfire at idle. The car will sometimes feel like...

    ACIS and a vaccumm leak?

    Looking up the resistance specs on the AFM, I have a couple questions about the tests. If it meets the resistance specs, is that a sign that its working? I've heard the TPS can still meet spec and not work, so I'm wondering if the same thing applies to the AFM. CRE, in another thread you...

    ACIS and a vaccumm leak?

    Noticed today that the sputter starts when the car just starts to warm up. We didn't notice this before, but now I'm starting to wonder if it's a sensor problem somewhere. What can do to help describe these problems better? I'm trying the best that I can, but I'm not that knowledgeable with...

    ACIS and a vaccumm leak?

    We're planning on doing that today. Gotcha, thanks. Definitely, we're not planning on rigging anything on this car unless we have to. Bad, lazy fixes will just cause me more problems later on. The previous owner had to replace to alternator, I had forgotten that, so it might explain...

    ACIS and a vaccumm leak?

    It's been awhile. Haven't had much of a chance to work on it this week. I ordered quite a bit of gaskets, the valve cover, valve cover #3, small ones for the valve cover #3 bolts. I figure that we'll figure the oil leakage problem, and while we're tearing stuff down we'll take a good hard...

    ACIS and a vaccumm leak?

    I plan on it. It's possibly there could be a leak somewhere. I figured that a fuel pump was either a "It works, or it doesn't" item, but I could be wrong on that. I'm not sure what codes he had. I had a 41, 21, and 43. 41 and 21 have gone away, leaving me with 43. I'm going to try...

    ACIS and a vaccumm leak?

    How nasty was the misfire? We swapped throttle bodies, and checked the plugs today and cleaned the oil out. On the first start up it idled pretty smooth, but on the highway it started sputtering, delayed reaction, and general lack of power. So the throttle body wasn't the issue at all in...

    ACIS and a vaccumm leak?

    We cleared most of the oil out of the plug wells. We'll go back and clear off the wires a bit more thoroughly. The plugs were almost completely underneath oil at first. But we cleared a good 90% of it out. It's no longer touching the plugs. Gotcha. I'll check for codes again. From reading...

    ACIS and a vaccumm leak?

    The plugs are pretty new, according to the previous owner. Same with the wires. It might be a good idea to change them. Before I do though, I want to try and get the TPS calibration out of the way so I don't spend a lot of money chasing ghosts. Will a TPS cause a miss, or can I just rule that...

    ACIS and a vaccumm leak?

    I mentioned earlier that we switched out the throttle bodies. I think the newer throttle body that we switched in might be connected to the misfire problem. I took my dad out with me on this second run, he said that gurgle I was describing is a pretty bad misfire. Before the highway run with...
