I just had an oil change and my air filter changed out 3 days ago. Tires rotated and pressure checked 4 days ago and when they checked pressure during oil change said they said it was way too high and let out air. Don't know if they were right anyway after that. Filled up with gas last night and went to work this morning, everything fine. Go to go to lunch and my engine light came on, cruise light blinking (tried reset in case I did hit it. Didn't work), and my vehicle dynamics control "off" lig

Need toyota expert please.I completely rebuilt the engine on my 1998 toyota camry. I drove it for 11 months with no problem. then the oil light came on. The oil level was fine . I checked the oil pressure with a manuel oil pressure guage and got 5-8 psi. I checked the oil pump and relief valve . I replaced the oil pump and had the same problem.I took off the valve cover and I do have oil on the top end of the motor. When I started the car the oil went up on the windshield of the car. I blew air

That does not happen only on Toyota.If you already replaced oil pump, and newly installed pump is working, there is no oil leak and you already checked oil lines to exclude blockage, that can be due to a cracked or incorrectly installed head ga ... Toyota Camry

Had oil changed 3 days ago...oil pressure had been fine until today. I drove about 3 miles and pressure became erratic and pegged high and then pegged low. It did this several times and then went to zero and stayed there. I checked the oil level and it is fine and there is no sign of oil in the coolant and the engine is running fine. Any idea what the problem is?? Is it just a pressure sending device or could it be the oil pump itself?? Thanks!!

Went to advance auto parts store and had some codes pulled for my check engine light. Theses codes came up P0113 IAT Sensor 1 Circuit High Input, and P0103 MAF or VAF A Circuit High input. My car stalls when I come to a stop and when I start it up it stalls right away unless I rev the engine and then when I get it going again I can't get past 45 miles per hour and the rpm guage races up to 4. The next day I started it up and it started idling high for a minute or 2 then slowly went down and

I have a 2000 Pontiac Firebird with 90,000 miles on it. I put in Gunk engine cleaner and ran it for 5 minutes as directed then drained the oil. I then did an oil change (Quaker State 10-30) and put in Lucas oil stabilzer (heavy duty). The oil pressure at idle is 90 psi and when driving it could go as high as 110 psi. I removed the oil pressure sensor and blew it out with compressed air and there was no change. If the sensor is faulty would it show high pressure? Do I have oil blockage or is the

The sensor can show high pressure when that is not the case, they fail high not low, take the sender out and plug in a mechanical guage to verify this, that is the only way to be 100% sure. ... Pontiac Firebird

2003 jeep grand cherokee 6cyl. Oil pressure drops as engine warms up.replaced sending unit, same. Checked with mechanic's pressure gauge and found out gauge on cluster is correct. Pressure drops below 5 when the engine is warm.Removed oil pan and found pickup screen was clogged by sludge.Replaced oil pump and screen, cleaned oil pan. Now pressure stays at 10 psi at idle when warm. However, it can not create pressure after start up, light stays on until you rev engine up and bring pressure close

The reason it differs from cold to hot is because your oil is thicker when cold, as the engine heats the oil thins a bit causing the drop. Good news is, you do not need but about 7psi at idle to keep the engine properly oiled. (to bring oil to the t ... 2002 Jeep Liberty

86 SS Monte Carlo losses oil pressure at high rpm's, I've checked the gauge and its accurate and put a larger oil pan on it and and a pick-up tube that came with the pan and changed oil pumps and at wide open throttle the oil pressure goes from 70 psi to 25psi and as soon as you let off the throttle it goes back to 60 to 70 psi and the motor has a pretty fresh rebuilt with about 10,000 miles on it, any suggestions on what to check next?

Fuel Problems I just purchased an 89 Ford F150 with a 302 and it will not start without ether or gas but once it starts it runs on its on and at idle is running rich (black smoke out of exhaust).

The check engine light stays on constantly and the fuel pump runs constantly and when I try to get self test codes the light never blinks..it just stays on.
