My wife and I have a 1997 eclipse, I bought it 3 years ago and well the worst thing I really had wrong up until recently was an oil leak around the front cover. That has been long fixed by replacing the gasket. Up until 3 months ago it was running great until one day it started a hesitation problem, every once in a while the rpms would suddenly drop and it would skip at idle, the only way to drive it was (and still is) to high idle it@2000rpms after first start and wait til it clears up (flooding?) or WOT to boost till it clears, and regained back power.
We decided to change out parts by looking online (dsmtuner threads) to see what could possibly be the problem culprit. We've changed the following parts; fuel pump, New trick flow fuel filter, FPR (stock as it ran great when I first put it together and it had a stock for to begin with), New Bosch plug wires and high heat plugs, throttle body (couldn't adjust idle with old one as it was worn out anyway), manual boost controller, MAF.
So far I've also tested some sensors as well. TPS it's good and IAC on the throttle body. Now it idles ok after first start (no WOT needed as of now but still skips till warm but, idles normally all day) but when boosted it will only go to 4 psi and hesitates beyond that.
I've tried to raise the boost pressure but when I do it hesitates worse. I also must say that it has a 1g engine and I have no EPROM upgrades on it for the 2g ECU but it has always ran great till now.
I did disable the + constant to the ECU so every time you turned the car off it would always reset so I wouldn't get the misfire code every 3 days and have to unplug the battery so often.
Well, I did reconnect it for a bit to find any other codes besides the ones I knew would show up and got one for the P0135 O2 heater wire bank 1 sensor 1. Can this cause boost problems?
If anyone knows please help. I've also done boost leak tests and there isn't any from what Jude seen so far but keep checking. I'm also thinking knock sensor, Maybe??
Don't wanna give up on this car...to good to us...thanks to anyone who can help...
