That scares me if these cars are so quickly put together that little "hiccups" like this occur.

*sigh* I need to buy a BMW or something.

Anyway, I believe my autotap can check fuel pressure through the PCM so I'll look into that. At idle it should be between 48-55psi you say?

When this happened I instantly looked at my autotap (always on) and had no KR, no codes, and nothing seemed out of the ordinary at first glance. Either way I should replace my fuel filter as typical maintenance since I doubt its ever been changed. Any other thoughts/

It may have just been a hiccup... Never know untill it really becomes a problem...

Yeah should be between 48-55 PSI.... I think that falls true for all series II engines..

It was a one time thing. Everything man made has error built into it. How many times in your life have you said..."I need to reboot" same thing.

I wouldn't even be considering this as ever happening and would be a six pack down the road from it.

You make me think of trying to explain to someone that their PCM is shot.... And they think I'm totally nuts... I give them the home PC explanation... If you left the PC on all of the time, sooner or later it would wear out.... Well the car has a computer too, sooner or later it may fail.... They still give me that odd look like I'm nuts...

But one in a rare while it is possible to have a hiccup....

Heck I was tinkering with my 95 today and it had a hiccup... Idle dropped to 200 then jumped back to 900 then went to idle and didn't do it again....LMAO

Haha...I leave my home pc on 24/7/365 ...never have any problems. lol

I caused a check engine light in the 97 when I cleaned the motor. The wires are original and when the water hit it ...OMG. It dried and the next day..no light. =0)

Sometimes the easiest and best fixes are the ones you don't make because hiccups don't count in life.

I also leave my pc on 24/7 365.. still going strong at two years.. along with all my other 3-16 year-old systems .

The problem, is people never really grasp how important the PCM is on a car. Without it, the car won't run. And it controls EVERYTHING.. especially on OBDII cars. I mean, the **** this thing deals with, is enough to make any mortal man cry just trything to control 1% by himself.

I had a hiccup yesterday...

Kyle, do you remember when you scanned my car at Gordy'* and found an intermittent misfire on cylinder 1? I finally got around to changing my plug wires to the 8mm Beldens, and I took some time to spray electronic cleaner in the primaries of each ignition coil and in the harness that hooks up to the ignition module. I let everything dry out, put everything back on the car with generous amounts of dielectric silicone grease, and started it up. The car ran like it was missing terribly but cleared up in a few minutes. I haven't had any CELs yet, so I assume everything'* fine and dandy. Maybe a little too liberal with the grease?

Anyway, just keep an eye on things (like you need me to tell you that) and keep the smart people updated with what'* going on.

Blasphemy!

I had the same exact "hiccup" last fall. It happened when I came to a stop and the engine started to shudder and it was below 500 rpm. Then the light turned green, I hit the gas and it dissapeared never to return again. It could be bad fuel. Thats the last time I fill up at Clark....
