First I do know that I don't truly have a gvr4 but a '92 base with a 4g63 slapped into it. From what I was told by the dude I bought it from is that the whole wiring harness was replaced to fit the engine (yr and car it came from is unknown) but somehow there is an Auto ecu mated with the engine. He also told me that sunroofs didn't come on these cars so the one I have is aftermarket. This thing also had a car phone installed sometime ago. So far I have replaced the struts, tie rods, oil pan gasket, front cover gaskets, timing belt, valve cover gasket, added a stock intercooler (yup you read that right it didn't have one when I bought it), boost gauge, 3" downpipe, 3" thrush glasspack, 3" performance cat, and dumped the exhaust out the passanger side in front of the tire (when bought had a slapped together evo exhaust scraping the ground). Pretty sure thats it but instead of enjoying my new investment it spent the first month in the driveway being worked on. Existing problems are that the power steering rack is leaking, pump not hooked up but driving the car, tach not working, high idle when cold, stumbling acceleration, battery and brake light pulse all the time but are lit up more when lights are on, and the rear bumper rotted out so driving around with just the beat up cover on no supports for now. My bro has two 1st gen lasers and has done a lot of FREE work on my car already so I know how to fix some of the things wrong but the problem area is mainly the high idle. I have checked for vacuum leaks and can't find any, checked for boost leaks and can't find any, and read that most problems are solved with the ficv. Am I on the right path? My second concern is the pulsing brake and battery dash lights. They don't come on all the way but are dim and pulse, I believe it's a bad ground but not sure where to start. Last but not least where does the tach hook up and where should I start with that? There are many connectors from the harness that are just hangin there with no place to plug in. Soooo Sorry for soooo much crp in a first post but I figured I would throw it all out there and give you guys a good laugh for the newbie. Any help would be appreciated, thanx
