Hello everyone,
I have a '93 TY, with a 20g turbo, 50lb injectors and a custom chip. I have been having issues with idle after warm up. Here is my issue: Once it warms up and is sitting at idle I notice it doesn't seem to quite run correctly. It'll bog down and then come back. I notice the needle on the battery gauge will also dip low and then come back once it evens itself out. The RPM's will go to 1 or below. It never dies, but seems to at times struggle to maintain a good idle with the way it bogs down and then back up.
It has become noticeable at a stop or stop-light as well. It does not do it all the time, but when it does it hesitates to accelerate for a split second before it'll go. (not always) Once again, it never dies though. If I run the heat or A/C it seems to bog down and do it more, once I turn them off it runs better, but will start again, just not a prominent as when they are on. I also have noticed that sometimes at night with the headlights on and coming to a slow and then accelerating the lights will go dim and then once I give it gas will come back brighter.
The air mixture will run 15.5 up to 16 or little more when it starts acting this way. Once I go it'll even out and run fine. It only does it at a stop or idle. Once moving and giving gas it does fine, or out on the road it has no issues. It also has no issues starting. Starts every time. I have replaced the battery, the fuel pressure regulator, ICV, spark plugs and gapped correctly and the cap and rotor, as well as cleaned the throttle body. I am confused as to why it could be doing this and perplexed as to why it only does it once it has warmed up or at a stop.
Any info or help on this would greatly be appreciated.
Thank you, all!
