Car sputtering under heavy load

now sounds like the perfect time to switch over to an external MSD coil and maybe ignitioin module. and replace the plugs and wires well your at it. and if its not ignition than oyu have a great ignition anyways.Inspecting and testing parts is better than the "throw money at it until it's fixed" method.

well being that u had a tps code and now it has a rpm flat spot u could very wel have a bad tps, tp sensors typically dont just die they will have bad spots, there is typicaly 2 ways of testing for a dead spot, watching voltage through a throttle swing or checking resistance through a throttle swing, both of which involve me to type way to much to explain

Yeah, the ignition will "eventually" be upgraded along when the direct port kit is installed, but that could still be 6-8 months off...so for right now I'll just try to correct the problem. I'm going to troubleshoot on saturday, school is kicking my ass right now.

unless you own a dsmI know a lot of people like to make jokes about DSMs, but what I was referring to should be applied to any vehicle. It goes along with the American way of driving a car until it breaks, rather than getting regular maintenance performed. Car owners are lazy and would rather take the quick solution.

Cap /rotor is an easy switch.
4 screws/8mm bolts will hold the cap onto the distributor. Take those out to remove the cap. Once you have the cap off look at the contacts inside the cap, chances are, especially if its an old distributor, that the contacts are either corroded and beat up, or there is little to no contact left.
The rotor inside the distributor is also held on with a single phillips screw. That one can sometimes be a whore to get off, and odds are that it is not working very well.
OBD 0 distributors always seem to have problems with the rotor especially.
First things first I would go ahead and and pick up a new cap/rotor, which you can get from any parts store in town. -
Alright, first thing I'm going to do on satuday is probably pick up a new cap and rotor...couldn't hurt right?
As far as checking the voltage on the tps I've got a voltmeter, and from what I understand on hondas it is .49 - 4.9, so I should just be able to have somone sit in the car and slowly open up the throttle while I watch the voltmeter, correct?

Alright, here's the question now:
Like I said, I'm not too familiar with the ignition on these motors. The ecu is obd0 and the head is a b16. Now, when I bought the car I can remember the seller telling me that the dizzy on their was either obd1 or and ls dizzy. I can't remember for sure, but I know something was different about it. So my question is, are caps/rotors interchangable between all the b-series?
Also, I've read up and found it could possibly be the ignitor....??? Sound possible?
-
When a honda ignitor dies they usually leave the car stranded.
OBD I distributor is unlikely as well, as you don't have an OBD 0 -> OBD 1 harness conversion installed. LS distributor would be noticeable because one of the ears of the dizzy would have to be cut off in order to bolt it to the b16 head. -
Hmm...I am going to inspect the dizzy tomorrow. But I am almost positive that he said he had to trim something in order to get the dizzy to work with the head. In the case that it is an LS dizzy, should I buy a cap and rotor for the b18a or for the b16? Come to think of it, it would be impossible to buy a cap/rotor for a obd0 b16 specific distributor, so I'd have to get the LS pieces, right (assuming they are different).
-
If you cut a leg off of the distributor it is an LS and you will watn a B18a cap/rotor. If not, some USDM parts will work on the OBD 0 b16 distributors. I think obd II GSR might be the correct fit, but do not quote me on that, as it has been a few years since I've had to round up OBD 0 dizzy parts.
