oil pressure gauge and poor idle help
 

I just buy a 97 rx7 3 weeks ago,and when I start my engine.The standard oil pressure gauge show to 4 after warm up then driving.I found sometime drop to 1 or 2 .I saw a post it may the connector dirty.or any other problems in my car?And also, when I start my car the idle rev is 2000 and after warm up 5 to 7 mins it also stand 900 to 1100 .How can fix this problems?

the oil pressure gauge is the sending unit, i just bought an aftermarket one and i my oil pressure is dreamy, then on the idle problem just tune ur TPS - throttle position sensor w/ a voltmeter. that should help a little bit.

When you start your car at least on the American versions the car has an automatic warm up which revs the engine to about 2K-3K rpms in order to warm up the engine faster. This is completely normal. In order to stop this just blip the throttle as soon as u start it up and it should return to the normal 900 to 1K rpm range.

ooohh.. wow, that is some sick ass information RXtacy, that really helps dude.. hhmm.. that explains an assload.. lol.. damn USDM cars.. haha.

Thanks ur infromation rx7tt and my cars using 70 litres can go around 220km is it normal?anything I need to check?

1. EVERY car made has a higher cold idle, usually between 1600-2000 rpm. This can be adjusted.
2. Clean or replace the oil pressure sensor unit. It is on the driver's side of the oil filter pedestal.
3. You either have a small vacuum leak or you need to adjust the idle a little bit. There is an air bleed screw under the intake elbow.

Also, if you start the car in gear (with the clutch in obviously) it will not rev up.

Thanks all guys help especialy TT Rotary .my car rev back to narmally .But funny thing is i just take off the tps connector have a look and turn a air bleed screw .my car 's rpm run 700-800 after warm up.but one more thing when i speed up my car and stop my car .the rpm is very very slow back to 700-800 so is t still good?
