I have a 98 Honda Accord 4 cyl. When you crank the car it cranks fine until you lift your foot off of the accelerator pedal. When you do that, the car shuts off? Any ideas
Do you
have the same problem?

Hi safet35, several things I would like you to check, one is, fuel pressure, I will send you a link that will show you how to do that, also I would like you to check the tps(throttel position sensor) and the idle air control valve as this is what stops your car from shutting off when your foot is released from the pedal, unless you have a fuel problem.

To check the IAC motor remove the unit, with the wires connected turn the key to the "on" position without starting the engine, the IAC should move in or out. If the IAC motor does nothing it has probably failed, replace it with a new unit and recheck system. Note: while the IAC motor is removed clean (use aerosol carburetor cleaner) the passages the IAC uses to control idle air speed

Just to let you know, the other day when the problem started. Every morning I just put the key in the ignition and never pump the gas before starting. I did the same thing the other morning except when it started, it revved up to over 3000 RPM and stuck there. I had to immediately shut it down fearing it would blow the motor.
I also ran the OBD II on it and got the following codes: P0420, P0401, P1456.
I should have given you this information earlier. Sorry.
I will check the fuel pressure and IAC this afternoon. How about the TPS? Testing it?

P0401 Exhaust Gas Recirculation Flow Insufficient Detected

P0420 Catalyst System Efficiency Below Threshold (Bank 1)

P1456 Leak Detected In EVAP Control System

codes are kind of vague, but, 401 can mean pcv valve, clogged, which, you should change anyway, because its such a cheap fix, also, the egr valve could be faulty, or Im guessing the egr tube is clogged, .420 could be a bad oxygen sensor on bank 1 or even a clogged, catalyctic converter, I would go with the oxygen sensor, but you can put your hand on the muffler really quick when you first get it started, to see if you can feel a strong pressure from the exhaust. No p1456, can mean a bad, fuel cap, or a bad evap canistor, or a hole in the evap canister hose. Try the gas cap first, so many people fail inspection just because of that, its pitiful, and a weak gas cap will give you a check engine light, we wont worry about the tps just yet.

OK.I haven't checked the fuel pressure yet have to find an adapter for my pressure gauge. However, was trying to take the two screws out of IAC to get it off so I could see if it was moving. Well I didn't have the right torx bit so got to go find one. It's not a 20 (big) 15 (To small) but I did crank the car and it stayed running. But I had the vacuum hose that connects from he brake booster to the manifold connection right next to the IAC. When I connect the hose back, the car shuts off. I took it off to make sure it was not clogged and the hose is clear. I left it off to move the car and of course I have no brakes w/out it. Still sound like the IAC?

Ok, im sure you have several things wrong here and yes it still may be, the iac. But you brought something to my attention with the brake booster vacuum, I want you to put it back on, try to get the car running, once you do, I want you to take a needle nose pler and pinch the hose closed, tell me what happens, also did you check/change the pcv? And also you will have to take a look at the egr, valve. There is a hose that, may be clogged too, (gas recirculatory code). Sometimes one of problems will cause three other codes.

Just wanted to let you know that I took the intake manifold off after finding the EGR port blocked. I was able to clean everything and bead blast it, polish it up and put it all back together. Car runs better than it has since we purchased it. All codes cleared.

Thanks for the help.
