Poor performance when warm...

[jebooker]

Well,this is an ongoing issue, unfortunately. The trouble is when my 93ATX warms up, i.e. when the temp needle hits the bottom line, the car lags, bogs, stumbles, and just dosen't perform as it should. The only code I get, after clearing, running, reading, 3 times is the 332 EGR. Is there a way to test the EGR to tell if it is bad?. I didn't think the EGR would affect the car in this way.

I've checked the DIS, replaced the Coil,TPS, and fuel filter. There is no oil in the plug wells, and the wires/plugs were recently replaced. It bucks when at "light" throttle, then when "opened up" it surges while the secondaries are opened.

I'm running out of ideas...I've cleaned the nostrils, MAF, sacrificed a chicken or two, but still no luck! As I said before, if I get in, turn the key and go, it runs strong, with no hesitation/stumbles, and the secondaries open immediately when I stand on it...Nirvana for 5 minutes. Thanks in advance...

Most likely it is your DPFE sensor. http://home.earthlink.net/~rcm_automotive/id14.html I don't get the whole "when it warms up thing" but I have a 93 atx and when my DPFE sensor went. It would not bog or anything if I lightly hit the gas(drove normal --- yeah really sucks) soon as I tryed accelerating to fast it would bog down.

"when it warms up" translates to; when the temp needle just barely moves from stone cold to the first line on the guage, and when the heater just starts to blow luke warm air...approx 5 min of driving @ 15 Degrees.

Any bench test for the DPFE??
