I could use some help and or advice guys. I have a 1g that's my dd. Its all stock 2.0 nt AT. I just painted it a few weeks ago and it was sitting for a couple weeks while I worked on it. Anyway, it used to fire right up as soon as I cranked it. Now its gotten harder to start. At first it would catch and idle low for a minute and slowly bring the rpms up to speed. It keeps getting worse and harder to start. As it sits now its very hard to start and it wont start good at all when its warm. Then last week I was driving around and it starts misfiring and sputtering bad. It had a horrible power loss and idled very low. The thing is, the misfiring etc will come and go. I drove it for a couple days and it didn't do it at all. Then out of nowhere it starts sputtering like that. Then it will drive fine for a couple days before it happens again. I will say as soon as it started sputtering I smelt something in the cabin. I got out and looked under the hood and didn't smell anything. Got back in the cabin and I could smell it.
Now, what I have done so far is put new plugs in that are gapped right. Swapped in new ignition wires. Swapped in new coil pack. Swapped in new power transistor. Pulled the ecu and looked for anything out of whack. It looked fine to me. I swapped the cas for one in my 2g. No change. Because of the hard start I put in a new coolant temp sensor. No change. Still hard to start. Bypassed the fuel pressure solenoid. Checked that the rail is getting fuel. I pulled my codes and it said barometer and IAT was bad. Got a new 1g mas and no change.
Now what gets me is that I have a palm that I can datalog with. Something is out of whack with it. Like I just put in the new coolant temp sensor and on the datalog its saying my coolant temp is -75 or something crazy. And after I swapped the mas I still get a code for baro and iat. Then I noticed the tps said it was at like 40% when closed. So I adjusted it to get it lower to like 20%. I observed it was at about 20% then a couple minutes later its back at 50% tps at idle. Im like . Im starting to think something is up with the ecu. I know I smelt something in the cabin when this started and I checked it out, but I didn't observe anything too bad I think. But I don't know what else to do.
Im just frustrated now one because one I don't know what else to do now, and 2 because I fix what the codes tell me to fix and I put a new cts in and I get no change on the datalogger. Like I said, next on the list is to get another ecu unless anyone has any other ideas. Thanks, Chris
