Hey guys
I just got my 1995 g20 on the road today and took her for a test drive. Well all seemed well till I came to a lite and it was idling funny, seemd like it was about to stall but it didnt. Then after that if I came to a dead stop then went to go again I could floor the gas petal and the car woulndt go anywhere untill a min or so then it would slowly start going. In park it goes up in idle then goes down in idle when I put it into drive the rpms dropp and sometimes stalls.

When Its Cold, the car idles and runs perfect untill it starts warming up is when I start having these problems.

CEL's-EGR Temperature Sensor (RH)
-Single Cylinder Or Multiple Cylinder Misfire
-Front Heated Oxygen Sensor Heater

-I checked the TPS and it was .4 and WOT 4.35.
-I pulled each sparkplug wire out and each one changed
-Timing isnt set but its just in the middle which shouldnt be way off to cause this.
-Replaced front o2 sensor
-Checked for vacc leaks but couldnt find any so there shouldnt be any major leaks if any.
-None of the EGR is being used. I have everything plugged up so its not leaking anywhere ( the reason I had to do this is bc the motor I got had the thread missing from the EGR pipe that goes into the top of the header.)

The motor is a USDM Highport

Any help or advice would be appreciated. Thank you

Check MAF voltage, MAF ground?

Re grounded MAF and still same problem.

Problem Fixed

It was the sparkplug wires. They were shooting spark from the side of the tube so not all the spark was going to the sparkplugs.

Thanks Guys

Glad I replaced mine this week! That's hard to see down in the well, glad to hear it was an easy fix.:biggthump
