Hey guys, I have a buddy that recently bought a 91 hatch for cheap, it needed a head gasket and a couple of other minor things. He changed the headgasket and what-not and had it running fine. Then out of the blue, it just started acting weird and would not start. He messed around with it for a couple of days before he realized that the screw had fallen out of the rotor and it was spinning freely on the shaft of the dizzy. He fixed that and now the car will not rev past 3K rpm's. I am thinking that the screw may have done some damage to the inside of the dizzy, but since there is a bolt stuck he could not get it off for me to look. Another thing to note...the car starts really hard some times and almost seems to backfire through the intake occasionally when trying to start it and other times it starts just fine. When it is running, it runs pretty smoothly except for the rev's problem. He said his timing is on, but he is still getting a TDC code (code . So, what do you think, something in the dizzy got fubared? Oh yea, it case it helps, this is a DPFI car.

 

there was a tread on this very subject like less than a week ago

 

Oh yea, did I mention that I try the search function and I found nothing. I also scrolled through the tech pages, but seeing as how not everyone gets real specific with the title of their post, that often does no good either.

 

yah sorry i didnt read the whole thing, o well good luck!

 

the car is in limp mode (rev limit @ 3k). replace the dist.

(psst, PERFECT time to do a MPFI swap.

 

Im curious, this is just a guess though. Did the screw need to be tightened to a certain ft/lb?? If so, that may be causing some problems. Im not sure but it seems like if it is too tight or too lose, it could be causing some problems with spark when starting and when revving past 3k.

 

Yea, I was pretty sure the dizzy was bad, I figure that screw that came out of the rotor did some damage. Now he just has to get the top mounting bolt out, it's stuck good and tight. Might just end up pulling the valve cover and undoing that whole top flange. He does want to do the MPFI swap, it's just hard to find the parts around here without paying an arm and a leg, but he is looking for them. Thanks mang.

 

Did he try using some big *** vice grips to get the bolt out?

 

Ok, he finally brought the car over to the shop, a little heat and some vice grips and I was able to get the bolt off Looking inside the distributor, I found the rotor screw that was previously MIA. He wanted to try it out with the screw out of the picture, still no worky So we start inspecting a little further and found a part of the distributor inside was bent, don't know all the names of the internal pieces but anyway, I had an old DPFI dist laying around and we put his coil in it, bolt it on the car and she fired right up. So, after him driving the car around for a week in "limp mode" I finally got to tell him....I TOLD YA SO, LOL. I got a full center console out of a 94 Integra in trade for the old DPFI dizzy, I think it is gonna make a real nice addition to my 91 hatch, armrests are nice

 

so what do "I" get?

good job
