Car Forum / Chrysler Cars / December 200492 Plymouth Acclaim
Trying to put a diagnoses on this problem. Whilel driving my 92 acclaim home it started Missing and had lose of power uphill.Although the car never overheated the temp gauge did go past midpoint. I checked the spark Plugs and regaped them ,but they looked and seemed fine. once I get the car started at a idle out of gear it doesn't seem to bad,but when i put it in gear and get it some gas it bucks and bangs. there is no Water in the Oil, I'm no mechanic,just wondering if the Car has had it,any help would be appreaicated. Thanks Ron > Trying to put a diagnoses on this problem. > Whilel driving my 92 acclaim home it started Missing and had lose of power > uphill.Although the car never overheated the temp gauge did go past > midpoint. Have you checked the oil to see if it has any coolant in it, or the coolant for oil? That will tell you if you have a head gasket failure. If that's OK, one easy and cheap thing you could do is a good quality injector cleaner in the gas. You can get that at any decent auto parts place. Make sure it is recommended for your type of car, fuel systems vary. Beyond that, you need to get the codes read. This is not difficult but requires a shop manual and some technical knowledge, so you need to have it done at a competent shop. It may be only a sensor, but you need a diagnosis to know for sure. Thanks for the advice,I did mention in my first post that the Oil was free of coolant and coolant free of Oil. I did run the car at a Idle with the Radiator Cap off it did not bubble up but it did come to the top of radiator into the overflow tank which seemed normal not sure with it not being under pressure. Will try the fuel injector cleaner and check the wires.

Well, the first thing to do is to check the computer codes. To check the computer codes: With the engine off, switch the ignition key on-off-on-off-on, leaving it "ON". Do not go to "start", just "on" during this procedure. Watch the "Check Engine" or "Power Loss" light. It will turn on, then go off, then will begin to flash-out any trouble codes that have been stored. For instance, if it flashes: flash <pause> flash flash <long pause> flash flash flash <pause> flash flash flash flash flash <long pause> flash flash flash flash flash <pause> flash flash flash flash flash Then you have a 12 (one flash followed by two) a 35 (three and five) and a 55 (five and five). 55 means "end of codes" or, if by itself, "No codes stored. Check the codes and report what you find. The next thing to do is to tell us how long it's been since the timing belt was replaced. DS Ok will try to do this this week.

Well, whoever you are, you get an A in theory and an F in real world. umm that would be me, max!! > > Not a timing belt problem, if the timing belt was off by one tooth it > > would throw the map sensor way off and cause low vacuum, what does low [quoted text clipped - 3 lines] > > Well, whoever you are, you get an A in theory and an F in real world. > Not a timing belt problem, if the timing belt was off by one tooth it would > throw the map sensor way off and cause low vacuum, One tooth? Cause enough vacuum change AT IDLE to throw the MAP sensor that far off? Nuh-uh. Several teeth, maybe. One tooth, not a chance. ok steve > > Not a timing belt problem, if the timing belt was off by one tooth it would > > throw the map sensor way off and cause low vacuum, [quoted text clipped - 3 lines] > > Nuh-uh.

Several teeth, maybe. One tooth, not a chance. Guys, not only will one tooth off screw up the MAP signal, having the belt tension too tight will do it also, especially in a cold climate. The MAP signal is sinusoidal, the SMEC/SBEC actually takes the amplitude of the signal into account. That is one reason ChryCo vehicles were/are so sensitive to MAP problems. The cam timing might be the problem, and it might -not- be the problem, but since it takes less than 2 minutes to check and verify, it would be reasonable to do so as part of the diagnosis. Ok just wanted to Let you guys know the status on this Acclaim. I have it in the shop and it is The Head. seems the Head Gasket blew and it muist have went a little at a time because the compression burnt some of the head away between 2 of the cylniders. So they sent the Head out to have a shop Helacoil (I think) Weld) the head and machine it then the guys will put it back together. Anyway Thanks for all the help. I have been monitoring this group some really interesting reading.Thanks Ron > Trying to put a diagnoses on this problem. > Whilel driving my 92 acclaim home it started Missing and had lose of power [quoted text clipped - 9 lines] > Thanks > Ron |
