1st (and the one that is irritating me the most) is the car is hard to start. This started to occur after I took it in to have a new flex pipe attached. It takes about 15-30 attempts before the engine turns over, the first 3 turn over successes, the engine revs to 1400, drops to 500, stutters and then dies. When I press on the gas, the rpm's drop instead of rise, causing it to die faster. After I get the engine to stay running, everything is fine except the rpms then idle high (1200) once the engine is warm, but stays around 850 while still cold and warming up. If i adjust the throttle to lower the idle to 850 when warm, the engine wont turn over at all in the mornings. After I have driven it though, as long as I don't let it sit for 6+ hours, the car starts right up immediately. The longer I let it sit (while at work or over night) it again goes through what I mentioned above. I've replaced plugs, wires, battery, filters, all fuses, it's still a good starter and alternator, belts are new. A mechanic reset my emission settings saying they were off, but that didn't help. I've read that it could be my ECU, or my air control, or a compression problem. Before I go spending too much more (already dropped 2k into trying to find why the car is doing this) I was hoping someone on here might be able to help. I have read through many of the already existing questions, and found a few that were labeled as a hot-start(?) but the symptoms were the reverse of what I'm getting.
2nd, and this might be in part with the above problem, when I'm driving over 70mph, I'll sometimes hear a slight whine. It sounds similar to what a turbo would sound like when it is about to die, however there is no turbo on this car.
3rd, there is a very slight knocking sound that can be heard when I am actively accelerating or reving. When I am coasting the knocking isn't there, or when slowly easing on the gas it is also not there. It's not loud, and not actually a knocking sound per se, but it is the only description i have for it, other then to describe it like the sound you'd hear from an idling go-kart engine or boat motor. I read that clogged lifters could make the sound, or irregular firing. It sounds like it is near the no.1 cylinder, but not actually in the cylinder.
Any help? Thanks and sorry for the novel-length. I'm new at rebuilding a car and engine from crap condition to road machine.
(Also quick question, is it possible to replace the 1.8 sohc in the 94 with a newer dohc/turbo engine? Or would the mountings not match? I'm looking at both a 95, a 99 and a 01 block for possible replacements, but not looking to replace the tran if possible.)
Thanks
