Today my car started hesitating or missing. The rpm tach was jumping around when i was holding it constant. The car ran poor like the wrong amout of fuel or spark. I pluged in data master and logged some in town driving.

What does Data Error in the top right box of data master mean? Its is usually Data Ok but data error pops up alot.

Could it be a ground or the pcm is loosing power for a second?

All of the tables still read when this error comes up, but no SES light, but it pulls the following codes only when the data error pops up. It only stays on for a 1/10 of a secound.

Code 34 MAP Low popped up once along with
66 A/C press sensor open/Short.
code 62 oil temp high came up once
code 24 output speed low came up once aswell

35 data errors in a five min run

I raced the car at the drags friday, ran fine 14.1
Raced the car autocross sunday car ran fine there too.

I'm not sure what happened to the car i didn't touch anything under the hood all weekend, it just started acting up.

Although i did change the oil pan gasket and timing cover gasket last week. the opti is orginal with 123,000 miles on it?

I can email the file to anyone, i don't have a web page to post it, sorry

The car idles like it has a cam, it acts like it has a mis.

Thanks brady

Car still idles like it has a cam, and still runs poor, like spark is off. Car does not sound right and runs very slow also.

 

We did some more logging on the car and its getting really bad on how it runs. You guys take a look at this a tell me what you think!
